Diastereoselective Synthesis of trans-N-Benzyl-2-(2-methylphenyl)-6-phenyl-4-piperidone
摘要:
Diastereoselective synthesis of trans-N-benzyl-2-(2-methylphenyl)-6-phenyl-4-piperidone (6a) was performed by cycloaddition of the aldimine (1c) with 2-silyloxy-1,3-butadiene in the presence of trimethylsilyl triflate. The use of the p-trimethylsilyl substituent of the aromatic ring of the aldimine gave high diastereoselectivity of the product.
