摘要

The regioselectivity of the acylation of Li enolates and silyl enol ethers is reported using acyl halides and acyl cyanides. We illustrate a simple method for the preparation of 1, 3- diketones via the silyl enol ether in excellent yields, free from competing O-acylation and diacylation products.
