Abstract

Abstract Four series of potential PAF-antagonists in which the isoxazole nucleus is condensed with a polyhydrogenated five-or six-carbon ring were prepared. The synthesis of the compounds 3-aryl-4, 5, 6, 7-tetrahydrobenz [c] isoxazoles 1, 3-arylcyclopent [c] isoxazoles 2, 3-aryl-4, 5, 6, 7-tetrahydrobenz [d] isoxazoles 3, and 3-arylcyclopent [d] isoxazoles 4, required an extensive optimization and comparison of the methods available ...
