Enzymatic resolution of chlorohydrins for the synthesis of enantiomerically enriched 2-vinyloxiranes

A series of vinylchlorohydrins are resolved by enzymatic kinetic resolution. The resulting R-alcohols, obtained in up to 99% ee, are stereoselectively converted into vinyloxiranes in high yield. The S-acetates, obtained in up to 99% ee were either deprotected to S-alcohols, or cyclized directly to vinyl oxiranes under basic conditions, with moderate to no loss in ee. The results are consistent with a racemization mechanism involving reversible migration of the acetate during deprotection. Georg Thieme Verlag Stuttgart.
A concise enantioselective strategy to (+)-(R)-goniothalamin and (+)-(R)-goniothalamin oxide by employing hydrolytic kinetic resolution and ring-closing metathesis as key steps

An efficient and general strategy to (R)-goniothalamin and (R)-goniothalamin oxide is described by using Jacobsen's hydrolytic kinetic resolution of racemic epoxide and ring-closing metathesis (RCM) as key steps, which provided a rapid access to these natural products that display a fascinating array of biological activity. (R)-Goniothalamin oxide was prepared in high yield and diastereomeric excess under various epoxidation conditions. Georg Thieme Verlag Stuttgart.
A short and general approach to the synthesis of styryllactones: (+)-Goniodiol, its acetates and β-trifluoromethyl derivative, (+)-7-epi-Goniodiol and (+)-9-deoxygoniopypyrone

(+)-Goniodiol, its acetates and β-trifluoromethyl derivative, (+)-7-epi-Goniodiol and (+)-9-deoxygoniopypyrone, the representatives of styryllactones have been synthesized in a short and general way. The key steps involve the regioselective asymmetric dihydroxylation and the palladium-catalyzed cross-coupling of cyclic allylic carbonate with vinyltributylstannane.
