Abstract

Process for preparing unsaturated 6-methyl-16-methylene-steroids of the general formula ** (See formula) ** in which X = H o well F Y = free or esterified hydroxy group R = H, OH where = 0 as well as its 1-dehydro derivatives, characterized in that a 6-methyl steroid of the formula is treated with chloranil ** (See formula) ** in which X and Y have the meaning stated above, R1 means H, H or R and A - B means (see formula) or ** (See formula) ** and, whenever R1 means hydrogen, a hydroxy group is introduced in position 11, by treatment with a hydroxylating microorganism in 11, as well as, in order to prepare the corresponding 1-dehydro derivatives, a double bond is additionally introduced in position 1.2. , by treatment with 2,3-dichloro-5,6-dicyano-p-benzoquinone or with dehydrogenating microorganisms in position 1,2.
