hexamethyldisilazide (LiHMDS) in THF, followed by reaction with electrophiles, leads to the formation of 4-substituted pyroglutamates in good yield. This approach has been used for the synthesis of the novel amino acid (4).
用二异丙基氨基锂(LDA)或六甲基二硅叠氮化锂(LiHMDS)在THF中将受保护的焦谷氨酸盐1(c),1(d),1(e)质子化,然后与亲电试剂反应,导致形成4-取代的焦谷氨酸盐产量高。该方法已用于合成新氨基酸(4)。
