Abstract

A procedure to prepare a 3-cyclopentyloxy-steroid of the general formula (I) **(See formula)** where X is **(See formula)** where R1 is a polycarboxyalkyl group, but can also be methyl when X has structure (A); Z is a carbonyl or hydroxymethylene group; R is a lower alkyl, ethynyl, or chloroethynyl group; and R2 is a lower alkanoyloxy group, characterized by (1) reduce a 3-cyclopentyloxy-steroid of the general formula (II). **(See formula)** where R1 and Z have the meaning set forth above, while the dashed line indicates an optional double bond at position 14, to form a 3-cyclopentyloxy-13beta-polycarboxyalkyl-gona-1,3,5 (10), 8-tetraen-17-one or -17-ol, a 3-cyclopentyloxy-13-polycarboxyalkyl-gona-1,3,5 (10) -trien-17-one or -17-ol or a 3- cyclopentyloxy-13-polycarboxalkyl-8alpha-gona-1,3,5 (10) -trien-17-one or -17-ol; O well (2) etherifying the 3-hydroxy group of a 3-hydroxy steroid of the general formula **(See formula)** where X1 has one of the meanings given for X or is **(See formula)** with an esterifying agent containing the cyclopentyl group, and, if desired, oxidizing a resulting 17-ol to 17-ketone, reducing a 17-ketone to 17-ol, alkylating, ethynylating or chloroethylating a 17-ketone to a 17alpha-alkyl-, ethynyl- or chloroethynyl-17beta- ol, enol-acylate a 17-ketone to delta16-17-alkanoyloxylic compound to 16alpha-hydroxy-17-ketone or 16alpha, 17-diol.
