, p. 1521 - 1522 (1998)
Total syntheses of avenaciolide and isoavenaciolide were achieved in six and three steps respectively based on starting chloropropargyl derivatives; the key step in such syntheses involves intramolecular alkoxycarbonylation of tungsten-η1-propa

The avenaciolide family of natural products are small α-methylene bis-γ-lactones that exhibit a wide variety of biological activities. Herein we report concise syntheses of five members of this family of natural products along with the synthesis of one no

A synthetic method using tungsten-π-allyl compounds is developed for total syntheses of natural bislactones including (+)-dihydrocanadensaolide (2), (±)-avenociolide (3), and (±)-isoavenociolide (4). Syntheses of these natural compounds are based on a com

Reduction of 3-chloro-4-oxoalkanoates 5 with bakers' yeast gave (4S)-3-chloro-4-hydroxyalkanoates, which were hydrolyzed and dehydrochlorinated to give (γS)-alkylbutenolides with >96% ee. Reduction of 5 with NaBH4 gave syn-3-chloro-4-hydroxyalkanoate 6. Asymmetric hydrolysis of syn-4-chloro-3-hydroxyalkanoate (±)-10 with lipase afforded (3R,4R)-6 and (3S,4S)-10 with high optical purities. Hydrolysis and dehydrochlorination of (3R,4R)-6 gave (γA)-alkylbutenolides with >85% ee. Total syntheses of (3aS,6aS)-ethisolide, whisky lactone, and (-)-avenaciolide from these butenolides are described.
Synthesis of (±)-isoavenaciolide and of (±)-ethisolide from (±)-7-oxabicyclo|2.2.1|hept-5-en-2-one

, p. 629 - 638 (2007/10/03)
A short total synthesis of (±)-ethisolide and (±)-isoavenaciolide was accomplished from (±)-oxanorbornenone respectively in 11 and 12 steps, using a radical cyclization as a key step.
