哌酸异常不愿进行N-2酰化似乎是由于电子效应,而不是空间/构象问题。一个适合探索这些问题的系统是通过方法组装的,该方法已经为相对立体化学和(L)或(D)构型的β -羟基- α -氨基酸产生了一个通用的构建块。1997爱思唯尔科学有限公司
The abnormal reluctance of piperazic acids to undergo N-2 acylation seems to be due to an electronic effect, not a steric/conformational problem. A system suitable for probing these issues was assembled by methods that have produced a versatile building block for beta-hydroxy-alpha-aminoacids of either relative stereochemistry and of either (L) or (D) configuration.
