3-Methyl-1-indanone is a derivative of 1-indanone.Its synthesis has been reported. The 1H and 13C-NMR spectra of 3-methyl-1-indanone has been reported. Biocatalyzed oxidation of racemic 3-methyl-1-indanone with high enanatioselectivity has been investigated.3-Methyl-1-indanone is suitable for the synthesis of branched alkyl indanes (BINs). It may be used in the following studies: · Synthesis of 2,2,3-tribromo-2,3-dihydro-3-methylinden-1-one and 2-bromo-3-bromomethyl-1H-inden-1-one. · As photosensitizers for the splitting of dimethylthymine dimers. · As a model to verify three-phase model in enantioselective gas-liquid chromatography. · (-)-(R)-3-methyl-1-indanone may be used as standard for comparing the optical rotatory disper sion curve with 1,3-dialkylindenes in the study of base-catalyzed 1,3 proton transfer in indene systems. · As an optically active sensitizer to induce asymmetry in trans-1,2-diphenylcylcopropane (DPC). · The dl-isomers of 3-methyl-1-indanone may be used in the synthesis of monomeric and trimeric 3-methyl-1-indanethione. 3-Methyl-1-indanone is a derivative of 1-indanone.Its synthesis has been reported.
