Reaction Steps
Following the general procedure of Example 282 and making non-critical variations but starting with the 17-butyrate esters of 17α,21-dihydroxy-16β-methyl-5α-pregn-9(11)-ene-3,20-dione, 17α,21-dihydroxy-16α-methyl-5α-pregn-9(11)-ene-3,20-dione or 17α,21-dihydroxy-5α-pregn-9(11)-ene-3,20-dione (Examples 192, 197 and 202) the corresponding 17,21-diesters, namely the 17-butyrate 21-acetate diesters of 17α,21-dihydroxy-16β-methyl-5α-pregn-9(11)-ene-3,20-dione, 17α,21-dihydroxy-6α-methyl-5α-pregn-9(11)-ene-3,20-dione, or 17α,21-dihydroxy-5α-pregn-9(11)-ene-3,20-dione are obtained.
