N-(4-methylbenzenesulfonyl)- pyrrolidines and piperidines by a tandem S(N)2-Michael addition reaction

A tandem S(N)2-Michael addition sequence has been developed for the preparation of N-(4-methylbenzenesulfonyl)- pyrrolidines and piperidines bearing functionalized side chains at C-2.

Carbon-Carbon Bond Formation via N-Tosyliminium Ions

Addition of carbon nucleophiles to cyclic N-tosyliminium ions, derived from α-hydroxy and α-methoxy tosylamides (5a,b and 6a,b, respectively) is described.In general, good to excellent yields were obtained when allyltrimethylsilane, 1-t-butyldimethylsilyl
