The first asymmetric synthesis of the trans-3,4-dimethyl-4-arylpiperidine opioid antagonist scaffold is reported. C-3 stereochemistry was established via CBS reduction and stereoselective anti-SN2' cuprate displacement of the derived allylic phosphonate. The resultant vinyl bromide was then elaborated to the target compound by Suzuki coupling and trans-selective 4-methylation. Extension of this methodology
报道了反式3,4-二甲基-4-芳基哌啶类阿片拮抗剂支架的首次不对称合成。C-3立体化学是通过CBS还原和衍生的烯丙基膦酸酯的立体选择性抗SN2'铜酸盐置换建立的。然后通过Suzuki偶联和反式4-甲基化将所得的乙烯基溴精制为目标化合物。该方法的扩展应允许对映体选择性地进入高度取代的哌啶环系统。
