Catalytic Asymmetric Synthesis of Both Enantiomers of Pyrrolizidines 223H’, 239K’, 265H’, and 267H’ Found in Madagascan Frogs (Mantella) and Their Affinities for Nicotinic Acetylcholine Receptor
摘要:
The asymmetric synthesis of pyrrolizidines 223H', 239K', 265H', and 267H' has been achieved starting from 1,5-hexadiene via a common synthetic intermediate 5. The affinity of both enanthiomers of 1-4 for nicotinic acetylcholine receptor was evaluated.
