The 1,3-dipolar cycloaddition of azomethine ylide derived in situ from the reaction of acenaphthylene-1,2-dione and 1,3-thiazolane-4-carboxylic acid to various exocyclic dipolarophiles synthesized from trans-androsterone and trans-dehydroandrosterone afforded a library of novel spiro[5′.2″] acenaphthylene-1″-one-spiro[16.6′]-(7′-aryl) -tetrahydro-1H-pyrrolo [1,2-c][1,3]thiazolo-trans-androsterone/ dehydroandrosterone hybrid heterocycles respectively. These reactions proceeded stereo-specifically affording a single isomer of the 16-spiro steroids in excellent yields.
