METHODS FOR THE PREPARATION OF 2,3,3A,4,5,7,8,9,9AB,9BADECAHYDRO - 3AB-PRIMARY LOWER ALKYL-7-OXO-1H-BENZ(E) INDENES AND 4,4AB,4BA,5,6,7,8,8A,9,10-DECAHYDRO-8AB-PRIMARY LOWER ALKYL - 3H-PHENANTHREN-2-ONES BY CYCLIZING COMPOUNDS OF THE FORMULA WHERE R1 IS HYDROGEN OR LOWER ALKYL; Z'' IS CARBONYL OR CH(OR2''); R2'' IS HYDROGEN, LOWER AKYL, LOWER ALKANOYL, BENZOYL, NITROBENZOYL, CARBOXY-LOWER ALKANOYL, CARBOXYBENZOYL, TRIFLUOROACETYL OR CAMPHORSULFONYL; T'' IS -C(X'')=CH-, -C(OR3)=CH- OR -Q''-CH2-; R3 IS LOWER ALKYL; X'' IS BROMINE, CHLORINE OR IODINE; Q'' IS CARBONYL, LOWER ALKYLENE DIOXY-METHYLENE, DI-(LOWER ALKOXY)-METHYLENE OR HYDROXY-METHYLENE, R4 IS LOWER PRIMARY ALKYL AND M IS AN INTEGER HAVING A VALUE OF 1 OR 2. THE COMPOUNDS OF THIS SERIES ARE USEFUL AS INTERMEDIATES IN THE SYNTHESIS OF KNOWN STEROIDS WHICH ARE PHARMACOLOGICALLY ACTIVE AS FERTILITY CONTROL AGENTS.
Abstract:
Total synthesis of known progestationally active steroidal materials. The steroids can be synthesized depending on the particular starting reactants selected by employing as intermediates bicyclic compounds of the formula
WHEREIN M IS AN INTEGER HAVING A VALUE OF 1 OR 2; R4 is hydrogen or lower alkyl; Z is lower alkylenedioxy, CH(OR2) and carbonyl; R8 when taken along is hydrogen; R9 when taken alone is lower alkoxycarbonyl, aryloxy-carbonyl, lower cycloalkyloxycarbonyl, carbonyl-halide, hydrogen, carboxy, formyl and methylene-X, where X is a leaving group and when taken together are methylene; with the proviso that when Z is carbonyl R8 when taken alone is hydrogen; R9 when taken alone is carbonyl halide, hydrogen, carboxy, formyl and methylene-X where X is a leaving group and when taken together are methylene and R2 is hydrogen, lower alkyl, lower alkoxy-lower alkyl, PHENYL-LOWER ALKYL, TETRAHYDROPYRANYL, LOWER ALKANOYL, BENZOYL, NITROBENZOYL, CARBOXY-LOWER ALKANOYL, CARBOXY-BENZOYL, TRIFLUOROACETYL AND CAMPHORSULFONYL AND REACTING THEM IN THE CASE WHERE R8 and R9 taken together are methylene or R8 is hydrogen and R9 is methylene-X with Beta keto esters and other analogs of the formula
WHEREIN R6 is selected from the group
LOWER ALKYL; R7 is lower alkyl; R15 is selected from the group consisting of oxo, lower alkylene-dioxy or (hydrogen and lower alkoxy); B is selected from the group consisting of lower alkoxycarbonyl-methylene, lower-aryloxy-carbonyl-methylene, cyanomethylene, lower alkyl sulfinyl-methylene, lower alkyl sulfonyl-methylene, and R25 and R26 are independently selected from the group consisting of hydrogen, hydroxyl and lower alkyl.
