␣,-Unsaturated ketones are not conveniently alkylated by radicals generated from tetraalkylstannanes via photoinduced electron transfer (PET), either by direct irradiation or when a singlet sensitizer (an aromatic nitrile, a pyrilium salt) is used. However, the procedure is successful with tetramet

BIRCH' demonstrated in 1950 that a steroidal a,p-unsaturated ketone (I) may be deconjugated to its p,y-unsaturated ketone isomer (III) by irreversible protonation of the conjugate anion (II), however, the requisite anion has been prepared only by indirect means (e.g. through the enol acetate, 132 fr
