A stereospecific method is described for the alkylation of acyclic amino acids (alanine and phenylalanine) which proceeds with retention of configuration. The method involves a) conversion of the amino acid to the predominantly 2-aryl-3-carbobenzyloxy oxazolidinones (2 and 8), b) alkylation of the potassium enolate with CH3I or PhCH2Br, c) Base hydrolysis and hydrogenolysis to afford the alkylated
描述了用于无环氨基酸(丙氨酸和苯丙氨酸)的烷基化的立体有择方法,其进行构型保留。该方法包括a)将氨基酸转化为主要的2-芳基-3-羰基苄氧基恶唑烷酮(2和8),b)用CH 3 I或PhCH 2 Br烯醇化钾烷基化,c)碱水解并氢解为得到烷基化的氨基酸。
