β-amino acid N-Boc-ADDA is prepared following a disconnection of the CC bond between the two E,E double bonds. The stereochemistry of the two synthons was controlled using the alkylation of chiral bromoallenes derived from naturally occurring (S)-serine and (S)-phenyllactic acid. The cupration of bromoallenes derived from (S)-serine also provides a general method for the synthesis of chiral β-alkylated
重要的天然β-氨基酸N-Boc-ADDA是在两个E,E双键之间的CC键断开后制备的。使用衍生自天然存在的(S)-丝氨酸和(S)-苯基乳酸的手性溴代烯烷基化来控制两个合成子的立体化学。衍生自(S)-丝氨酸的溴丙二烯的铜化也提供了合成手性β-烷基化的天冬氨酸衍生物的通用方法。
