Protected lactic acid enolates have been alkylated with a range of electrophiles to give the substituted adducts with moderate to excellent stereoselectivity. A chiral protected glycolic acid adduct has also been doubly alkylated with high stereoselectivity.
被保护的乳酸烯醇化物已经与一系列亲电试剂烷基化,以产生具有中等至优异的立体选择性的取代的加合物。手性保护的乙醇酸加合物也已经以高的立体选择性进行了双烷基化。
