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 ##STR1## WHEREIN M IS AN INTEGER HAVING A VALUE OF 1 OR 2; R.sub.4 is hydrogen or lower alkyl; Z is lower alkylenedioxy, CH(OR.sub.2) and carbonyl; R.sub.8 when taken alone is hydrogen; R.sub.9 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 R.sub.8 when taken alone is hydrogen; R.sub.9 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 R.sub.2 is hydrogen, lower alkyl, lower alkoxy-lower alkyl, phenyl-lower alkyl, tetrahydropyranyl, lower alkanoyl, benzoyl, nitrobenzoyl, carboxy-lower alkanoyl, carboxy-benzoyl, trifluoroacetyl and camphorsulfonylAnd reacting them in the case where R.sub.8 and R.sub.9 taken together are methylene or R.sub.8 is hydrogen and R.sub.9 is methylene-X with .beta.-keto esters and other analogs of the formula ##STR2## wherein R.sub.6 is selected from the group consisting of ##STR3## and lower alkyl; R.sub.7 is lower alkyl; R.sub.15 is selected from the group consisting of oxo, lower alkylenedioxy or (hydrogen and lower alkoxy); B is selected from the group consisting of lower alkoxy-carbonyl-methylene, lower-aryloxy-carbonyl-methylene, cyanomethylene, lower alkyl sulfinyl-methylene, lower alkyl sulfonyl-methylene, and R.sub.25 and R.sub.26 are independently selected from the group consisting of hydrogen, hydroxyl and lower alkyl.
