| Abstract: | By using 3-pyrrolidone derivatives as a source of the D ring, the following five diazasteroids were synthesized: 8,16-diaza-2,3-dimethoxy-15,15,16-trimethylgona-1,3,5(10),13-tetraen-12-one (VII), 8,16-diaza-2,3-dimethoxy-16-acetylgona-1,3,5(10),13-tetraen-12-one (X), 8,17-diaza-2,3-dimethoxy-17-acetylgona-1,3,5(10),13-tetracn-12-one (XI), 8,16-diaza-16-acetylgona-1,3,5(10), 13-tetraen-12-one (XII), and 8,17-diaza-17-acetylgona-1,3,5(10),13-tetraen-12-one (XIII). |
