    摘要： 1. A PROCESS FOR THE PREPARATION OF A DESA-ANDROST-9EN-5-ONE OF THE FORMULA:

    2-R3,3-R1,3-R2,3A,6-DI(H3C-),7-(O=),X-PERHYDRO-5A,6-

    DIDEHYDRO-BENZ(E)INDENE

    WHEREIN R1 IS HYDROXY, LOWER ALKANOYLOXY, CARBOXYLOWERALKANOYLOXY, BENZOYLOXY, TETRAHYDROPYRANYLOXY, BENZYLOXY, BENZHYDRYLOXY, TRITYLOXY, ALLYLOXY, OR LOWER ALKOXYLOWER ALKOXY; R2 IS HYDROGEN OR LOWER ALKYL; R1 AND R2 TAKEN TOGETHER ARE SELECTED FROM THE GROUP CONSISTING OF (17B-OH, 17A-LOWER ALKANOIC ACID LACTONE), LOWER ALKYLENEDIOXY AND OXO; R3 IS HYDROGEN, LOWER ALKYL, HYDROXY, LOWER ALKANOYLOXY, CARBOXYLOWERALKANOYLOXY, BENZOYLOXY, TETRAHYDROPYRANYLOXY, BENZYLOXY, BENZHYDRLOXY, TRITYLOXY, ALLYLOXY, OR LOWER ALKOXY-LOWER ALKOXY; AND X IS A SUBSTITUENT IN THE 6- OR 7-POSITION SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, LOWER ALKYL, LOWER ALKYLTHIO, LOWER ALKANOYLTHIO AND HALOGEN; COMPRISING ESTERIFYING AN 11-HYDROXY-ANDROST-4-EN-3-ONE HAVING THE FORMULA:

    3-(O=),11-(HO-),16-R3,17-R1,17-R2-ANDROSTAN-4(5)-ENE

    WHERE R1,R2,R3 AND X ARE AS ABOVE; TO FORM A LEAVING GROUP IN THE 11-POSITION SELECTED FROM THE GROUP CONSISTING OF TOLUENE SULFONATE, LOWER ALKYL SULFONATE AND NITROPHENYL SULFONATE; SUBJECTING THE RESULTING ANDROST-4-EN-3-ONE WITH THE LEAVING GROUP IN THE 11-POSITION TO OXIDATIVE RING OPENING TO FORM THE CORRESPONDING 5 - OXO - 11 - (LEAVING GROUP)-3,5-SECOA-NORANDROSTAN-3OIC ACID, FORMING AN ALKAI METAL SALT OF SAID ACID; AND PYROLYZING SAID ALKALI METAL SALT BY HEATING SAID ALKALI METAL SALT TO A TEMPERATURE OF ABOUT 200*C. TO ABOUT 350* C. TO FORM SAID DESA-ANDROST-9-EN-5-ONE.

    摘要： Chalcogenated polyacenes including organic semiconductors such as tetrathiotetracene, tetraselenotetracene, and hexathiopentacene are produced by reaction of a polyacene with elemental sulfur, selenium, and tellurium in the presence of nitrogen-containing hot solvents, preferably alkylated amides. N, N-dimethylformamide is the preferred solvent. The disclosed method of synthesis produces substituted polyacenes of high yield and purity in considerably shorter reaction times than achievable by prior art methods.

    摘要： This invention is directed to processes for the preparation of desA-androst-9-en-5-ones and desA-pregn-9-en-5-ones which comprises subjecting the corresponding androst-4-en-one or pregn4-en-3-one respectively to the sequential steps of ozonolysis pyrolyzation, halogenation and dehydrohalogenation. The intermediate products produced in accordance with the processes of this invention can be converted into steroid end products of the 9 Beta , 10 Alpha -series which are pharmacologically useful as anabolic and progestational agents.
