Dithioketal derivatives of 13-polycarbonalkylgon-4-en-3-ones |
January 25, 1977 |
| Novel 3-thioketals of 13-polycarbonalkyl-17-ethynyl-17-hydroxygon-4-ene and 13-polycarbonalkyl-17-chlorethynyl-17-hydroxygon-4-ene, with improved separation of activities, i.e. maximizing progestational and minimizing androgenic action, are prepared from the corresponding 3-carbonyl |

Synthesis of 13-alkyl-gon-4-ones |
May 25, 1976 |
| The preparation of 13-methylgon-4-enes and novel 13-polycarbonalkylgon-4-enes by a new total synthesis is described. 13-Alkylgon-4-enes having progestational, anabolic and androgenic activities are prepared by forming a tetracylic gonane structure unsaturated in the 1,3,5(10),9(11) a |
