Abstract
A procedure for the preparation of steroid 21-dicyclohexylmethyl carbonates corresponding to the general formula ** (See formula) ** and especially: a) the mixed carbonate of dicyclohexylmethyl and dexamethasone, b) the mixed carbonate of dicyclohexylmethyl and of prednisolone, c) the mixed carbonate of dicyclohexylmethyl and of cortisone, d) the mixed carbonate of dicyclohexylmethyl and of hydrocortisone, e) the mixed carbonate of dicyclohexylmethyl and 9-alpha-fluorohydrocortisone, f) the mixed carbonate of dicyclohexylmethyl and prednisone, g) the mixed carbonate of dicyclohexylmethyl and of 9alpha-fluoro prednisone, h) the mixed carbonate of dicyclohexylmethyl and of 9alpha fluoro prednisolone, i) the mixed carbonate of dicyclohexylmethyl and beta-methasone, j) the mixed carbonate of dicyclohexylmethyl and of parametasone, k) the mixed carbonate of dicyclohexylmethyl and of 6-methyl-prednisolone, l) the mixed carbonate of dicyclohexylmethyl and of 9alpha-fluoro-16alpha-hydroxy prednisolone, characterized in that the chosen cortisone derivative is reacted with the dicyclohexylmethyl chloroformate in the presence of a tertiary base , such as pyridine, preferably operating in an organic solvent, such as dioxane or acetone.
