Ferrarini, Renan S.,Dos Santos, Alcindo A.,Comasseto, Joao V.
, p. 10601 - 10610,10 (2012/12/13)
The naturally occurring butanolides (-)-blastmycinolactol, (+)-blastmycinone, (-)-NFX-2, (+)-antimycinone as well as the four stereoisomers of the butenolide Acaterin were prepared in high enantiomeric purity using hydroxy-vinyl tellurides as starting mat

Brief syntheses of (+)-blastmycinone and related γ-lactones from an asymmetrically dihydroxylated carboxylic ester
Berkenbusch, Thilo,Brueckner, Reinhard

A method for synthesizing optically active trans,trans-configurated α,β,γ-substituted γ-lactones is presented. Asymmetric hydroxylation of ester 8 with AD mix α (AD mix β) and subsequent dehydration provided butenolide S-6 (R-6). Conjugate addition of Li2(Me2PhSi)2Cu(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.
