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 vinylbromide was then elaborated to the target compound by Suzuki coupling and trans-selective 4-methylation. Extension of this methodology
