The first stereoselective total synthesis of the immunosuppressive decalin derivative
monascusic acid B has been accomplished from (R)-(+)-pulegone involving Horner–Wadsworth–Emmons and Julia–Kocienski olefination reactions
and Lewis acid catalyzed intramolecular Diels–Alder cyclization.
Key words
monascusic acid B - total synthesis - (
R)-(+)-pulegone - Horner–Wadsworth–Emmons olefination - Julia–Kocienski olefination
- intramolecular Diels–Alder cyclization - immunosuppressive effect
