Some common heterocyclic compound, 60899-34-5, name is 1-Oxo-2,3-dihydro-1H-indene-4-carbonitrile, molecular formula is C10H7NO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Application In Synthesis of 1-Oxo-2,3-dihydro-1H-indene-4-carbonitrile
To l-oxo-2,3-dihydro-7H-indene-4-carbonitrile INT-1 (42.5 g, 0.27 mol) and (i?)-2-methylpropane-2-sulfinamide (36.0 g, 0.30 mol) in toluene (530 mL) was added titanium tetraethoxide (84.1 mL, 92.5 g, 0.40 mol) and the reaction mixture was heated at 60C for 12 h under N2. The crude (i?)-N-(4-cyano-2,3-dihydro-lH- indene-l-ylidene)-2-methylpropane-2-sulfinamide INT-4 was used directly in the next experiment. LCMS-ESI (m/z) calculated for Ci4Hi6N2OS: 260.3; found 261.1 [M+H]+, = 3.19 min.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 60899-34-5, its application will become more common.
