Preparation of 6-Hydroxy-2H-pyran-3(6H)-one from 2-Furylcarbinol by Photooxidation. Synthesis of a Pheromone of Vespa orientalis
摘要:
Photooxidation of 2-furylcarbinols followed by reduction with triphenylphosphine afforded 6-hydroxy-2H-pyran-3(6H)-ones in excellent yield. The method was applied to synthesis of 6-undecyltetrahydro-2-pyrone, a pheromone of Vespa orientalis.
