Abstract
A process for preparing a thioketal of the formula (II) ** (See formula) ** where R5 is a methyl, ethyl, ethynyl or chloroethynyl group, R4 is a hydrogen atom or an acyl group and n is 2 or 3, characterized in that, according to the known methods, a corresponding ketone of the formula (III) where n is 2 or 3, it is alkylated by reaction with a metal organ reagent that provides the R5 group with consequent formation of a tertiary carbinol; and optionally the 17beta-OH group is esterified.
