摘要:
NOVEL 3 - CYCLOPENTLYOXY - 13 - POLYCARBONALKYL-17AETHYNYLGONA-3,5-DIEN-178-OLS AND 17-ACYLATES, OPTIONALLY SUBSTITUTED AT C6, C7, C10 AND C16 WITH MTHYL GROUPS (1) ARE HORMONALLY ACTIVE AS PROGESTATIONAL AGENTS WITH LONG DURATION OF ACTIVITY AFTER ORAL ADMINISTRATION. 17-ACYLATED COMPOUNDS (1) ARE PROVEDED BY ENOLACYLATING AND ACYLATING, IN ONE STEP, THE CORRESPRONDING 13-ALKYL-17A-ETHYNYLGON-4-EN-3-ON-17B-OL EITHER WITH A REGENT COMPRISING ACETIC ANHYDRIDE AND AQUEOUS PERCHLORIC ACID IN A NON-POLAR, INERT ORGANIC SOLVENT, PREFERABLY ETHYL ACETATE, OR AN ANHYDRIDE IN ADMIXTURE WITH AN ACYL HALIDE AND AN ACID ACCEPTOR, AND THEN CARRYING OUT AN EXCHANGE REACTION BETWEEN THE 3-ENOL ACYLATE-17-ACYLATE FORMED THEREBY AND CYCLOPENTYL ALCOHOL; AND THE 17-OLS ARE PROVIDED BY ETHYNYLATING THE CORRESPONDING 17-ONES. IN CONTRAST TO THE PRIOR ART PROCEDURE WHICH REQUIRES BLOCKING THE 3KETO GROUP AND PROLONGED REACTION TIMES, ENOL ACETYLATION WITH ACETIC ANHYDRIDE AND AQUEOUS PERCHLORIC ACID CAN BE COMPLETED IN FIVE MINUTES AT ROOM TEMPERATURE.
摘要:
A PROCEDURE IS DISCLOSED FOR THE SELECTIVE PREPARATION OF STEROIDAL FORMATE ESTERS FROM CORRESPONDING STEROID ALCOHOLS. PRODUCTS FORMED BY THE CONVERSION ARE NOT ONLY HORMONALLY USEFUL IN THE ANIMAL BODY BUT ARE ALSO USEFUL FOR FURTHER REACTIONS OF THE STEROID NUCLEUS.
摘要:
TREATMENT OF A 13-ALKYLGONA-1,3,5(10),8-TETRAENE WITH ORGANIC PERACID RESULTS IN THE FORMATION OF A CORRESPONDING 8,9-EPOXY-13-ALKYLGONA-1,3,5(10)-TRIENE, WHICH UPON TREATMENT WITH ACID, IS RING-OPENED AND REARRANGED TO THE CORRESPONDING 13-ALKYLGONA-1,3,5(10),9(11)-TETRAEN-8-OL. CATALYTIC HYDROGENATION THEN AFFORDS THE CORRESPONDING 13-ALKYLGONA-1,3,5(10)-TRIEN-8-OL WHICH UPON DEHYDRATION GIVES THE CORRESPONDING 13-ALKYLGONA-1,3,5(10),7-TETRAENE. THERE IS THUS PROVIDED A ROUTE TO THE SYNTHESIS OF EQUILIN AND RELATED COMPOUNDS.
