Abstract: The invention comprises (1) a process for preparing steroids having, apart from substituents at the 16- and 17-positions, the formula <FORM:0912036/IV (b)/1> (wherein R is CHOH, CHO Acyl or CO) which comprises dehydrating and isomerizing with an acidic reagent the corresponding 11b -hydroxy-11a -methyl-5a -steroids; and (2) as new steroids, 17b  - hydroxy-11-methylene-5a -androstan-3-one and the 17-acetate and -propionate thereof, 3b ,20b -dihydroxy - 11 - methylene-5a -pregnane and the diacetate thereof, 11-methylene - 5a ,25D - spirostan-3-one and 3b -hydroxy - 11 - methylene-5a ,25D-spirostan and the 3-acetate thereof.  The process may be performed in one operation using formic, perchloric, sulphuric or toluene-p-sulphonic acid which may be dissolved in a lower fatty acid or anhydride or mixture thereof, or in two stages using thionyl chloride in pyridine at -20 to 40 DEG C. to effect dehydration to an 11-methyl-D 9(11)-5a -steroid which is then treated with formic acid in an inert solvent or one of the other acids referred to above in a lower fatty acid.  If the starting material is a 3b ,11b -dihydroxy steroid it may be wholly or partially transformed by the acidic treatment into a 3-acyl derivative of the 11-methylene product, which may then be saponified to the free hydroxy compound or fully acylated.
