| titleOfInvention | A PROCEDURE FOR THE PREPARATION OF THE COMPOUND 1,2-ALPHA-METHYLENE - 6,7 - ALPHA - DIFLUORMETHYLENE - 20 - ESPIROX - 4 - EN-3-ONA. |
| abstract | A process for the preparation of the compound 1,2-α -methylene-6,7- α -difluoromethylene-20-spirox-4-en-3-one, which consists of reacting the compound 1,2- α -methylene-20-spiroxa-4-, 6-dien-3-one A) with trimethyltrifluoromethyl tin; or B) with an alcohol to produce a ketal at position 3 and then reacting the latter compound with sodium chlorodifluoroacetate; or C) with metachloroperbenzoic acid to produce the 6,7- β -epoxy derivative and then reacting the latter compound with difluoromethylene triphenylphosphorane; and isolating the desired product thus obtained.
