Enantioselective catalyst efficiency for the synthesis of the camptothecin family was improved through ligand-tuning. Key intermediates of two convergent syntheses of camptothecin (Curran's intermediate and Corey's intermediate) were obtained in up to 10 g scale through the catalytic enantioselective cyanosilylation of ketones.
Pig liver esterase catalyzed hydrolyses of diesters. A new route to the syntheses of achiral half-esters
Ager,Prakash
, p. 739 - 742 (2007/10/02)
Pig liver esterase catalyzed hydrolyses of diesters of alkanes, aromatic and heterocyclic compounds gave high yields of the corresponding half-esters under mild reaction conditions.

Compounds of the formula STR1 wherein R1 and R2, which may be identical to or different from each other, are each hydroxyl or lower alkoxy R3 is cyano or --CO--Y; Y is hydroxyl, lower alkoxy, or a primary or secondary, substituted or unsubstituted, aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic amino group; and non-toxic, pharmacologically acceptable acid addition salts thereof. The compounds as well as the salts are useful for the treatment of circulatory and coronary disorders.
A SIMPLE SYNTHESIS OF 3-SUBSTITUTED FURANS. THE PREPARATIONS OF DENDROLASIN, PERILLENE AND CONGENERS
Tanis, Steven P.
, p. 3115 - 3118 (2007/10/02)
The Grignard reagent 7, derived from 3-chloromethyl furan, reacts with various alkyl- and allylic halides, in the presence of Li2CuCl4, to provide high yields of 3-substituted furans.
