Summary: Two macrocyclic keto-lactones, zeralenone (1) and
zeralanone (2),are reduced by fresh Bakers' yeast at various
substrate-to-cellratios and pH values and under both aerobic and
anaerobicconditions. Two substrates are reduced with
oppositediastereoselectivity, resulting in alpha/beta-diastereomers 3/4and
5/6, respectively. Zeralenone (1) produces 3/4 at ratio ofapproximately
1:3-4 and 6%-10% total yield (as determined byHPLC), while zeralanone (2)
produces 5/6 at approximately 2:1ratio and 15%-25% yield. The highest
conversion (ca. 28%) wasachieved with zeralanone (2) at pH 7.5-8, under
aerobicconditions. The opposite diastereoselectivity for reduction
ofzeralenone (1) and zeralanone (2) is ascribed to differentconformations
of the macrocyclic ring in solution.
Keywords: Bakers' yeast, reduction, diastereoselectivity, alpha-zeranole, alpha-zeralenole.

Summary: The CD spectra of some resorcyclic acid macrocyclic
lactones(RAL) are reported. The spectra of the E,Z-isomeric ketones 1,6are
very similar in shape and magnitude. The Cotton effects ofthe
7alpha-alcohols 2 and 7 are also of the same shape, but thedelta epsilon
values of 7 are only ca. 50% of those of theothers. The E-7beta-ol 3 gives
a completely different CD, whereasin the Z-series 8 shows a similar CD
curve as 6 and 7, but withagain reduced magnitude. The CDs of the acetates
4 and 5 are verysimilar to those of the corresponding alcohols 2 and 3,
resp. Theeffect of the 7alpha- and 7beta-hydroxy or acetoxy group on
theabsolute conformation of the "chain" from C(5) to C(10) is
thustransmitted to the absolute value of the torsional angle of
theinherently chiral chromophore C(11)-C(12)-C(12a)-C(1a)-C(=O)O in2,3 and
4,5, resp. The CD spectra of the E,Z-isomers do notexhibit straightforward
correlation with the configuration aroundthe C=C double bond.

Summary: Diastereomeric mixtures of resorcyclic acid macrocyclic
lactones,7alpha,beta-O-acyl zearalenols (1,2 and 3,4, full
name:trans-3,4,5,6,9,10-octahydro-14,16-dihydroxy-3-methyl1H-2-benzoxacyclo
tetradecin-1-ones (3S,7S or 3S,7R), and7alpha,beta-acyl zearanols (5,6 and

enzoxacyclotetradecin-1-ones (3S,7S or 3S,7R) arehydrolyzed by lipases.
Kinetic separation affords 7beta-alcoholswith complete site-selectivity and
nearly completediastereoselectivity. Among lipases examined, those
fromPseudomonas sp., Pseudomonas fluorescens and Candida cylindraceaexhibit
the broadest substrate specificity. In all cases7beta-alchols are major
products, diastereomeric excess (d.e. in%, determined by HPLC) approaches
100% for 1,2, 80% for 3,4, andvaries between 10% and 90% for 5,6 and 7,8,
respectively. Fasterand less stereoselective hydrolysis is observed
for7alpha,beta-O-chloroacetyl derivatives 3,4 and 7,8 as comparedwith
acetyl derivatives 1,2 and 5,6. The effect of ionic strengthand of organic
cosolvent on the rate and selectivity is studied.Explanation of
stereoselectivity of this enzymatic reaction isbased on the conformational
properties of macrocyclic ring aroundthe chiral acyloxymethine center C(7).
Perturbation by the localhelical arrangement of the two trimethylenic
side-chains attachedto this center renders 7beta-O-acyl diastereomers much
morereactive counterparts.

Summary: Kinetic and thermodynamic activation constants were
determinedfor both directions of heptamolybdate ion
(HM)-catalyzedepimerization of two aldopentoses, D-xylose===D-lyxose. They
arerelated to CD data for (aldose-HM) complexes, and to similarkinetic and
thermodynamic data previously reported for twoaldohexoses,
D-glucose===D-manose equilibrium. The results areconsistent with
Michaelis-Menten type kinetics, are a reveallower binding affinity for
pentoses as compared to hexoses of thesame configurational series, raised
by the stronger perturbationon binding of the former, and followed by
somewhat lower rates ofepimerization. A minimal kinetic mechanism is
presented, as wellas a refined transition-state structure, as compared to
thatrecently reported, involving a d-p interaction between Mo(VI)atoms and
the acetalic form of aldose.

Summary: Racemic methyl, ethyl and cyanomethyl
3-(2'-nitrophenoxy)butanoated 4-10, chiral precursors
of2,3-dihydro-1,5-benzoxazepin-4(5H)-ones with ACE inhibitoryactivity, were
prepared and submitted to kinetic resolution by aseries of commercially
available lipases. Best results (e.e.'sveće 99%) were obtained with
Pseudomonas fluorescens andPseudomonas sp. lipase. The structure of the
alkyl ester groupinfluences the rate of hydrolysis. Cyanomethyl esters 5
and 8were more reactive than alkyl esters 4,6,7,9 and 10. Chiral1H-NMR
shift reagents revealed 70-90 % e.e. for the remainingR-(-)-esters in
hydrolyses of rac. 4,6, and 9, and 99% e.e. inhydrolyses of rac. 7 and
10. A large effect on the rate andenantioselectivity of the hydrolysis of
esters 4,6 and 9, isobserved when a methyl group, which is remote from the
chiralcenter and from the reactive ester group, is on the aromaticring.
Keywords: Esters of 3-(2'-nitrophenoxy)butanoic acid, enzymatic kinetic resolution, structure vs. rate and enantioselectivity of hydrolysis.
