    Summary: Photochemistry of 4-methylene-2-adamantanone (1) have been studied under direct and sensitized irradiation. Direct irradition of 1 in benzene afforded 3:1 mixture of 2-methylenenoradamantane and 4-methylenebyciclo(3.3.1)undec-2-ene-7-al. Irradiation of 1 in benzene in the presence of benzophenone gave oxetane, the addition product of benzophenone to double bond, while the major product in the acetone sensitized photolysis were identified as syn- and anti-4-(3-oxobutyl)-2-adamantanone.

    Summary: As a part of our continuing interest in the strained rings system, we have studied the ring closing reactions of 1-(bromomethyl)-2-bromoadamantane (1), 1-(chloromethyl)-2-bromoadamantane (2) and 1-(bromomethyl)-2-chloroadamantane (3) with sodium and alkyl lithiums. The formation of cyclopropane product, 1,2-methanoadamantane (4), was achieved in good yield only in the reactions of 3 with sodium. The reactions of 1 and 2 with sodium gave as the major product 1-methyladamantane (5) or 4-methyleneprotoadamantane (6) depending on the used solvent. However, in the reactions of 2 and 3 with alkyl llithium the major products were the corresponding adamantane monohalides.

    Summary: Due to rigid geometry, adamantane serves as a ideal model for the studies of long range effects in satureted polycyclic systems. We found several long range C-F couplings in a NMR spectra of 2-chloro-4-(didehydrofluoromethyl)-2,4-(dimethylmethano)adamantane. Complete asignation of the structure was obtained by NOESY, RELAYH and HMQC experiments.
    Keywords: long range effects, CF-couplings

    Summary: In order to study the cyclopropane ring-opening reactions, we chose symmetrical and unsymmetrical cyclopropyl ketone, 2,8-didehydro-90noradamantanone (3) and 2,4-didehydro-5-brendanone (4), respectively, as well as several their derivatives. The protonation of cyclopropane ring and ring-opening reactions of 3 and 4 were carried out under the influence of chemical reagents such as electrophilec, nucleophiles and radicals.

    Summary: 1-(2-Phenyl-2-adamantyl)amines, derivatives of anaesthetic andanalgetic phencyclidine (PCP) were prepared in good yield starting with 2-amino-2-adamantylcarbonitrile and phenylmagnesiumbromide. 2-Amino-2-adamantyl carbonitriles were prepared in one step using two methods: at pH 1-6 and via bisulfite addition product.

    Summary: A series of selectively deuterated isotopomers of 2-adamantanone, 2-methylene-d2-adamantane and 6-methylene-d2-2-adamantanone were prepared, and deuterium isotope effects were measured in their C-13 NMR spectra and compared with the effect in the spectra of adamantane isotopomers. The long range effects delta 3, delta 4, delta 5 and delta 6 were observed and explained by aninteraction of deuterium through the adamantane cage. These effects confirm the hypothesis that deuterium behaves like other"real" substituents.
    Keywords: isotopomers of adamantane derivatives, long range effects, effectof carbonyl group, interaction through the cage

    Summary: Synthesis and reactivity of 1,2-methanoadamantane (1), a molecule which possesses a twist bent sigma bond incorporated in the adamantane framework, have been studied. 1,2-Methanoadamantane is chemically inert to nucleophiles and free radicals, but it is reactive toward electrophiles and could be easily catalitically hydrogenated. The reactivity of 1 is consistent with the bond distortion of central cyclopropyl bond in a trans fused bicyclo(4.1.0)heptane unit. The HOMO of 1,2-methanoadamantane is associated with central cyclopropyl bond but it seems likely that outside cyclopropyl bonds also suffer a substantional increase in the strain energy.

    Summary: A series of hitherto unknown macrocyclic thioethers with 1,3-bridged adamantyl system has been synthesized. The synthesis of 4,6:12,14-di(1,3-adamantano)-1,9-dithiacyclohexadecane (3), 4,6:12,14:20,22-tri(1,3-adamantano)-1,9,17-trithiacyclotetracosane (4) and 5,7:15,17-di(1,3-adamantano)1,11-dithiacyclocosane (15) have been achieved by intermolecular cyclization of corresponding terminal dibromides with thioacetamide using a high-dilution technique. Their structural aspects were derived from spectroscopic measurements and X-ray crystallography. Analysis of X-ray crystal structures 3 and 4 reveals a pronounced preference for gauche placement at C-S bonds. This preference is expressed by crown thioethers generally and is diametrically opposite that shown by crown oxaethers. In the continuation of our studies we have investigated potential application of various rearrangement reactions in the preparation of macrocyclic hydrocarbons. It has been shown that the transformation of macrocyclic thioethers to ring-contracted hydrocarbons can be effected conveniently by a reaction sequence of m-CPBA oxidation followed by a Ramberg-Baecklund rearrangement. Ramberg-Baecklund rearrangement of bissulfone 6 lead to the 3,5:10,12-di(1,3-adamantano)cyclotetradecane-trans,trans-1,7-diene (7) along with 3,5:10,12-di(1,3-adamantano)cyclotetradecane-cis,trans-1,7-diene (8) and 3,5:11,13-di(1,3-adamantano)-7,9-dehydro-8-chlorocyclopentadec-1-ene (9) as a minor products. The structure of 7 is established by spectral and X-ray crystallographic determination. In solid stat 7 displays approximately rectangular shape made up of antiplanar torsions along its sides, with gauche and anticlinal torsions at each corner. The conformational behaviour of diene 7 was analysed by dnamic NMR spectroscopy. Dynamic NMR studies indicated that 7 is conformationally mobile. At low temperatures ring inversion in 7 becomes slow on the NMR time scale, whereas at room temperature the molecule rapidly interconverts from one conformation to another. The ring inversion of diene can most reasonably be interpreted in terms equilibrium process between diastereomeric conformers 7a and 7a'. Using the coalescence temperature method, the transition state free energy was estimated to be ca. 14.2 kcal/mol.

    Summary: The synthesis and reactivity of 2,3-methano-2,4-didehydro-11-homoadamantanone, derivative of(4.1.1)propellane (1) are described. (4.1.1)Propellanone is chemically inert to nucleophiles, oxygen and free radicals, but it is reactive toward electrophiles and could be easily catalitically hydrogenated. The reactivity of 1 is explained by decreased electron density at the back side of the inverted carbon atoms and energy of HOMO of (4.1.1)propellanone, due to negative inductive effect of the carbonyl group placed in the alfa-position to the central propellane bond.
    Keywords: intramolecular cycloaddition, 2,3-methano-2,4-didehydro-11-homoadamantanone, inductive effect, propellanones, carbenes
