The preparation of S-(-)-6-methyl-2-piperidinone from S-alanine and R-(-)-5-methyl-2-pyrrolidinone from S-glutamic acid and their conversion into S-2-methyl-1-azoniatricyclo1.6>tetradecane (2a) and R-2-methyl-1-azoniatricyclo1.6>tridecane (2b) with enantiomeric excesses of 95 and 92percent respectively are described.The use of these compounds as phase-transfer catalysts did not lead to significant asymmetric induction.
