Anwendungen
VerwendenCyclopropanecarboxaldehyde reacts 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 cyclopentene.
Darstellung
synthetischeCyclopropanecarboxaldehyde is prepared by reaction of cyclopropylmethanol. The reaction needs reagent pyridinium chlorochromate and solvent CH2Cl2 with other condition of ambient temperature for 3 hours. The yield is about 60%.
