This report describes a new synthesis of the four stereoisomers of 1-amino-2-hydroxycyclohexanecarboxylic acids [(1S,2S)-, (1R,2R)-, (1S,2R)- and (1R,2S)-c6Ser], four conformationally constrained serine (Ser) analogues, possessing a six-membered carbocyclic ring. Initially, we synthesised cis-c6Ser and trans-c6Ser in their racemic forms, using as key steps the Diels–Alder reactions of methyl 2-benzamidoacrylate
该报告描述了1-氨基-2-羟基环己烷羧酸的四种立体异构体的新合成方法[(1 S,2 S)-,(1 R,2 R)-,(1 S,2 R)-和(1 R,2 S)-c 6 Ser],四个构象受限的丝氨酸(Ser)类似物,具有六元碳环。最初,我们合成了顺式-c 6 Ser和反式-c 6以外消旋形式存在的Ser,作为关键步骤,分别使用2-苯甲酰胺基丙烯酸甲酯与Danishefsky的二烯和1-甲氧基-1,3-丁二烯的Diels-Alder反应。旋光形式是通过拆分方法获得的。
