THE SYNTHESIS OF (+/-)-ISOPTYCHANOLIDE BY APPLICATION OF THE α-ALKYNONE CYCLISATION

The first synthesis of racemic isoptychanolide (2), a stereoisomer of natural ptychanolide (1), which differs in the configuration of the oxirane function, is reported.The key steps were an α-alkinone cyclisation (5 4, gas phase flow thermolysis at 62

SYNTHESIS OF A STEREOISOMER OF PTYCHANOLIDE

A stereoisomer of ptychanolide 1 was synthesized by a method which includes an α-alkynone cyclization.
