Piperidinyl aziridine N-phosphonate underwent ring opening in Grignard addition catalyzed by a copper reagent to yield trans 3-amino-4-alkyl-piperidines. The nucleophilic addition occurred trans to the aziridine group and regioselectively at C-4 position of the piperidine ring. The high regioselecti
%Alkyl-and 2-aryl-1,3-benxodithioles are obtained in high yield by the reaction of Grignard reagents or lithium alkyls with 2-alkoxy-1,3-benaodithioles,themaelves available in one step from anthranilic acid. In connection with our studies of the reactions of acyl carbanion equivalents with organobo
