Pyridinomorphinans: Asymmetric synthesis of either enantiomer and opioid receptor binding selectivity
摘要:
Either enantiomer of a new class of morphinans in which the aryl ring is replaced by a pyridine ring can be prepared by sequential iminium ion-allylsilane cyclization and intramolecular Heck insertion. Pyridinomorphinan 5 exhibits high affinity for the mu opioid receptor. (C) 1997 Elsevier Science Ltd.
