Novel tricyclic Delta(2)-isoxazoline and 3-oxo-2-methyl-isoxazolidine derivatives: synthesis and binding affinity at neuronal nicotinic acetylcholine receptor subtypes

A group of novel tricyclic Delta(2)-isoxazolines (4b, 5b, 7a-b, and 8a-b) and 3-oxo-isoxazolidines (6a-b and 9a-b), structurally related to cytisine or norferruginine, was prepared through 1,3-dipolar cycloadditions involving suitable olefins and bromonitrile oxide. The target compounds were assayed...
