Abstract

Oestriol derivs. are of formula (I): (where R1 is free esterified or etherified OH or halogen; R2 and R3 are free, esterified or etherified OH; R4 is H or free, esterified or etherified OH). (I) are e.g. prepd. by (a) reacting an oestrane-series 11-methylene steroid having an aromatic A ring with diborane; and oxidising the product with H2O2 to give the corresp. 11beta-hydroxymethyl deriv.
