A practical synthesis of enantiopure N-carbobenzyloxy-N′-phthaloyl-cis-1,2-cyclohexanediamine by asymmetric reductive amination and the Curtius rearrangement
摘要:
Enantionterically pure N-carbobenzyloxy-N'-phthaloyl-cis-1,2-cyclohexanediamine was synthesized by the asymmetric reduction of a beta-enamino ester formed from benzyl 2-oxocycloliexanecarboxylate and (R)-phenylethylamine, followed by hydrogenolysis, phthaloylation, and the Curtius rearrangement.
