Efficient Asymmetric Synthesis of α-Trifluoromethyl-Substituted Primary Amines via Nucleophilic 1,2-Addition to Trifluoroacetaldehyde SAMP− or RAMP−Hydrazone
摘要:
[GRAPHICS]An efficient asymmetric synthesis of alpha -trifluoromethyl-substituted primary amines via nucleophilic 1,2-addition of alkyllithium reagents to trifluoroacetaldehyde SAMP- or RAMP-hydrazone followed by benzoylation and SmI2-promoted nitrogen-nitrogen single bond cleavage is described.
