A Short Synthesis of Benzomorphane Analgesics (±)-Metazocine and (±)-Phenazocine
摘要:
A three step synthesis of (+/-)-metazocine and (+/-)-phenazocine starting with 3,4-lutidine is described. The key step involves Lewis acid promoted lithiation/electrophilic substitution reaction of N-alkyl-3,4-dimethyl-1,2,5,6- tetrahydropyridine.
