Lomevactone (INN; developmental code nameDR-250) is adrug described as apsychostimulant andantidepressant which wassynthesized and assayed in the 1980s, but was never marketed.[1][2]

Stereoisomers

[edit]

There are eight possiblestereoisomers of lomevactone. It is the (3R,4R,6R)-form that has the psychotherapeutic properties.[3][4]

(3R,4R,6R)-Lomevactone

Synthesis

[edit]

The conjugate 1,4-alkylation reaction between 4-chlorobenzylideneacetone (1) andphenylacetonitrile (2) gives 3-(4-chlorophenyl)-5-oxo-2-phenylhexanenitrile (3). The selective reduction of the keto group to the alcohol withsodium borohydride gives 3-(4-chlorophenyl)-5-hydroxy-2-phenylhexanenitrile (4). Hydrolysis of the nitrile to an acid gives 3-(4-chlorophenyl)-5-hydroxy-2-phenylhexanoic acid. This is followed by lactone formation completing the synthesis of lomevactone (5).
