| titleOfInvention | Method for obtaining 6-alkylideneandrost-1,4-dien-3-one |
| abstract | By a process comprising subjecting the corresponding 6-alkylidene-4-androsten-3-one to a 1,2-position dehydrogenation in the presence of a quinone, a silylating agent and a strong acid, a compound of the general formula (I) Wherein R is H or alkyl; R 1 and R 2 are independently of each other H, OR 3 , OC (═O) R 4 or O— (GPH) (where R 3 is , H, C 1 -C 6 alkyl or aryl; R 4 represents H or C 1 -C 6 alkyl; and GPH is a hydroxyl protecting group); or R 1 and R 2 together with the carbon atom to which they are attached form a carbonyl group or equivalent or a cyclic ketal) 6-alkylideneandrost-1,4-dien-3-one.
