Studies in Potential Antifertility Agents: Part XXIV - Synthesis of 2,3-Disubstituted 4'-(&β-dialkylaminoethoxy)propiophenones

Rao, K. V. B.,Iyer, R. N.

, p. 54 - 58 (2007/10/02)

A number of 2,3-disubstituted 4'-(β-dialkylaminoethoxy)propiophenones (32-41) have been synthesized as the structural analogs of a potent antifertility agent erythro-2,3-diphenyl-4'-(β-pyrrolidinoethoxy)valerophenone (1).Compounds 34, 35, 38 and 40 show cent per cent activity at dose levels of 2.5, 10, 10, 10 and 1 mg/kg, respectively.The structure activity relationship has also been discussed.
