A range of substituted pyridyl amino acids have been prepared by palladium catalysed cross-coupling of serine-derived organozinc reagents with differently substituted halopyridines. Following this procedure a DMAP analogue has been synthesised and used as a building block in the preparation of two related tripeptides, which have been tested as catalysts in the kinetic resolution of trans-2-(N-acetylamino)cyclohexan-1-ol, resulting in modest enantioselectivity.
通过钯催化丝氨酸衍生有机锌试剂与不同取代的卤代吡啶的交叉偶联,制备了一系列取代的吡啶基氨基酸。在此过程中,合成了 DMAP 类似物,并将其用作制备两种相关三肽的构件,在反式-2-(N-乙酰氨基)环己烷-1-醇的动力学解析中将其作为催化剂进行了测试,结果具有适度的对映选择性。
