  Brief syntheses of (+)-blastmycinone and related γ-lactones from an asymmetrically dihydroxylated carboxylic ester

  摘要：

  A method for synthesizing optically active trans,trans-configurated alpha,beta,gamma-substituted gamma-lactones is presented. Asymmetric hydroxylation of ester 8 with AD mix alpha (AD mix beta) and subsequent dehydration provided butenolide S-6 (R-6). Conjugate addition of Li-2(Me2PhSi)(2)Cu(CN) to S-6 followed by alkylation of the resulting enolate led to the stereopure silyllactones 9-11. They furnished the title compounds after oxidative removal of the Me2PhSi group. (C) 1998 Elsevier Science Ltd. All rights reserved.

  A simple and efficient method for the asymmetric synthesis of α-alkylidene-β-hydroxy-γ-butyrolactones and related natural products was developed on the basis of the catalytic asymmetric tandem Michael–aldol reaction and simple transformations. The synthetic utility of this method was illustrated by the facile synthesis of trisubstituted γ-butyrolactone natural products.

  A new lactone synthesis was developed using the Fischer chromium carbene complex. The lactone was formed from an alkyne bearing a hydroxyl or silyloxyl group in a tether, along with carbene carbon and carbon monoxide of the chromium carbene complex. Using this procedure, (+)-blastmycinone and (+)-antimycinone were synthesized from (S)-ethyl lactate in short steps.

  Titanium-mediated aldol reactions of 1 and (S)-2-tert-butyldiphenylsilyloxy aldehydes (matched pair) afford syn Felkin diastereomers in excellent yield and absolute stereochemical control. Having established that chain length does not affect the yield of the titanium aldol reactions we have been able to achieve short, high yielding and enantioselective syntheses of NFX-2 and Antimycinone.

  Chiral α-silyloxy ketones participate in highly stereoselective TiCl4-mediated aldol reactions that afford diastereomerically pure syn–syn adducts in high yield irrespective of the R1 and R2 substituents flanking the carbonyl or the silicon protecting group. Further manipulation of the resulting aldol adducts provide in a straightforward manner highly functionalized fragments that facilitate the synthesis
