Two series of novel steroidal isoxazolines and oxazolines were synthesized through different routes fromdehydroepiandrosteroneacetate and pregnenolone acetate, respectively. The synthesis of the analogs of both series is multistep and proceeds in good overall yields. While the key step in the synthesis of former is the cycloaddition of aromatic nitrile oxides across alpha,beta-unsaturated olefins
