Abstract
Title compds are of formula (I) where X = H and Y = OH or a (1-20C) ester residue or X+Y tog=keto; R3 = 3-keto-DELTA4-, 3-keto-DELTa4x6-, 3-OR-DELTA3,5 or 3-OR-DELTA4,6 and Or is ether or (1-20C) ester residue R6 = H, Cl, F, dichloro or Me, but is F, Cl or H (and R3 is 3-keto-DELTA4-) when R7 = 6,7-CH2; R7 = H or 6,7-CH2 and must be the latter if R6 = H; R13 = Me or Et R17 = a (1-5C) ether or (1-8C) ester residue; and R21 = H F, Oh or a (1-20C) ester residue.
