Application

(6R,7aR)-3-amino-8,8-dimethyltetrahydro-4H-3a,6-methanobenzo[d]oxazol-2(3H)-one is an N-amino cyclic carbamate (ACC) auxiliary developed in the Coltart lab used for the enantioselective α-alkylation of ketones. ACC alkylation offers a number of advantages including facile introduction, removal and recovery of auxiliary, high enantioselectivity, and access to the α,α-bisalkylated product.

The Journal of organic chemistry (2018-09-12)
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
