Use：: Cyclopropanecarboxaldehyde can react with Grignard or organolithium reagents to give the expected secondary alcohols. These are susceptible to ring opening in the presence of HBr, providing stereoselective access to homoallylic bromides. It is also used in the synthesis of eta(2)-enonenickel complexes by reacting with [Ni(cod)(2)] (cod = 1,5-cyclooctadiene) and PBu(3) and to prepare a cyclopropylidene tetralone which underwent an enantioselective palladium-catalyzed [3+2] TMM cycloaddition providing a chiral spiro-fused cyclopentene1-2. It is also a reagent in the preparation of N-alkylphenylalaninamides of pyridinylphenyland oxobipyridinylamines as human GPR 142 agonists for potential use as anti-diabetic agents and the cytochrome P 450 inhibition3.
