Remarkable O(2)-effect in 1,4-additions of diethylzinc to 6-acyloxy-2H-pyran-3(6H)-ones and 6-alkoxy-2H-pyran-3(6H)-ones

.   

Abstract

Under the influence of air, a facile 1,4-addition of diethylzinc to acyloxypyranones and alkoxypyranones 1 takes place. Reaction of diethylzinc with molecular oxygen provides EtOOZnEt, which catalyzes the addition of diethylzinc.
