A SHORT-STEP SYNTHESIS OF ANTIBIOTIC A26771B UTILIZING THE RING-OPENING REACTION OF β-ETHYNYL-β-PROPIOLACTONE

Abstract
The total synthesis of antibiotic A26771B was completed in short steps from 15-hydroxy-3,4-hexadecadienoic acid which was easily prepared by the ring-opening reaction of β-ethynyl-β-propiolactone with Grignard reagent in the presence of a copper(I) catalyst.
