cis-(3R,4R)-N-(tert-Butoxycarbonyl)-4-methyl-3-(methylamino)piperidine, a key intermediate for the synthesis of CP-690550 (a potent protein kinase inhibitor), is prepared via an asymmetric approach starting from ethyl 1-benzyl-3-oxopiperidine-4-carboxylate hydrochloride in an overall yield of 49%. The mild conditions and high yields obtained during the synthesis suggest a potential industrial application for this route.
cis-(3R,4R)-N-(叔丁氧羰基)-4-甲基-3-(甲氨基)哌啶是合成 CP-690550(一种有效的蛋白激酶抑制剂)的关键中间体,通过不对称反应制备该方法以1-苄基-3-氧代哌啶-4-甲酸乙酯盐酸盐为原料,总收率为49%。合成过程中温和的条件和高产率表明该路线具有潜在的工业应用前景。
