| titleOfInvention | A process to introduce a double bond at position 15,16 of a steroid |
| abstract | A process for the preparation of a compound of formula (I): ** Formula ** where R1 is a (C1-C4) alkyl and R2 is H or methyl, which comprises the reaction of a compound of formula (II) with a base: ** Formula ** where: R1 and R2 are as defined above; R3 is -COR4, R4 is a (C1-C6) alkyl, a phenyl optionally substituted with 1 to 3 (C1-C4) alkyl or a benzyl in which elphenyl is optionally substituted with 1 to 3 (C1-C4) alkyl; where the base is selected from a metal carbonate; a metal bicarbonate; a metal hydroxide; metal unhydride; a metal acetate; ammonia; and an amine of formula NR5R6R7 where each of R5, R6 and R7 independently represents H; a (C1-C6) alkyl optionally substituted with unhydroxy; or a cycloalkyl (C3-C6) (and at least one of R5, R6 and R7 is not H); or R5 is H and R6 and R7 form, together with the nitrogen atom to which they are attached, a saturated heterocycle of 5 to 7 members that may optionally contain other heteroatoms selected from O and N. |
