TOTAL SYNTHESIS OF (+)-PRELOG-DJERASSI LACTONIC ACID

Optically active Prelog-Djerassi Lactonic Acid 1 was synthesized from D-glucal; the crucial point being the elaboration of the carboxylic group as shown eq. 1 and 2 which involve the sequential process asymmetric addition of methyl anion onto the hete
