Ring closing metathesis employing the well-known Grubbs' ruthenium catalyst
has been used as the key step in the synthesis of piperidine alkaloids, (-
)-coniine and (-)-pipecoline, and the asymmetric induction has been perform
ed by using (R)-alpha -methyl benzylamine as an auxiliary. (C) 2001 Elsevie
