The α-alkylation of ketones is a fundamental synthetic transformation. The development of asymmetric variants of this reaction is important given that numerous natural products, drugs, and related compounds exist as α-functionalized ketones or derivatives thereof. We previously reported our preliminary studies on the development of a new enantioselective ketone α-alkylation procedure using N-amino cyclic carbamate (ACC) auxiliaries. In comparison to other auxiliary-based methods, ACC alkylation offers a number of advantages and is both highly enantioselective and high yielding. Herein, we provide a full account of our studies on the enantioselective ACC ketone α-alkylation method.

手性非外消旋N-氨基环状氨基甲酸酯Hy的形成，烷基化和水解：酮的对映选择性α-烷基化方法

酮的α-烷基化是基本的合成转化。鉴于许多天然产物，药物和相关化合物以α-官能化的酮或其衍生物形式存在，因此开发该反应的不对称变体非常重要。我们以前曾报道过使用N-氨基环状氨基甲酸酯（ACC）助剂开发新的对映选择性酮α-烷基化程序的初步研究。与其他基于辅助方法的方法相比，ACC烷基化具有许多优势，并且具有高对映选择性和高收率。在此，我们全面介绍了对映选择性ACC酮α-烷基化方法的研究。
