A general and cost-effective route has been developed to synthesize 1-heteroarylsubstituted cycloalkylamines from readily available heteroarylacetate in good yields. This synthesis features a LHMDS promoted cyclization and one-pot hydrolysis/Curtius rearrangement. This route can be easily carried out on multi-gram scale and be also used to prepare 1-arylsubstituted cycloalkyl/cycloheteroalkylamines
已经开发了一种通用且成本有效的途径,以容易的产率从易得的杂芳基乙酸酯合成1-杂芳基取代的环烷基胺。该合成具有LHMDS促进环化和一锅水解/柯式重排的特点。该途径可以容易地以克为单位进行,并且还可以用于制备1-芳基取代的环烷基/环杂烷基胺。1-杂芳基/芳基取代的环烷基/环杂烷基胺是通用的构建基块,它们在有机和药物化学中的应用已在吗啉和N-甲基哌嗪类似物以及已知的Rho激酶抑制剂化合物9的合成中得到证明。
