Enantioselective Total Synthesis of Chondrosterins I and J by Catalytic Asymmetric Intramolecular Aldol Reaction Using Chiral Diamine Catalyst

The first enantioselective total synthesis of chondrosterins I and J was accomplished. The synthetic method focuses on an intramolecular aldol reaction through catalytic asymmetric desymmetrization using chiral diamine catalyst. An intensive investigation of this reaction improved the enantiomeric excess up to 92 percent ee. In addition, stereoselective reduction of the ketone moiety efficiently converted chondrosterin I to chondrosterin J.

On a new synthesis of sterpurene and the bioactivity of some related Chondrostereum purpureum sesquiterpene metabolites

Sterpurene, a sesquiterpene hydrocarbon metabolite of Chondrostereum purpureum, a plant pathogen and potential mycoherbicide, was synthesized by a six-step sequence, in 33% overall yield. The key steps were a thermal [4 + 2] (Diels-Alder) cycloaddition of

Silicon in Synthesis. 21. Reagents for Thiophenyl-Functionalized Cyclopentenone Annulations and the Total Synthesis of (+/-)-Hirsutene

1-(Trimethylsilyl)-1-(phenylthio)ethylene (1) reacts with cyclic α,β-unsaturated acid chlorides to give β-mercaptophenyl-substituted cyclopentenones, whereas 1-(trimethylsilyl)-2-(phenylthio)ethylene (2) under similar conditions results in thiophenyl migr
