A highly enantioselective Michael addition reaction of α,α-disubstituted aldehydes to β-nitrostyrenes has been developed. In the presence of rosin-based chiral primary amine-thiourea, γ-nitroaldehydes I [ Ar = 4-NO2C6H4, 2-NO2C6H4, 4-CNC6H4, 4-CF3C6H4, 4-FC6H4, 2-furyl, etc.; R1 = Me, Et; R2 = Et, n-Pr, Ph, etc.; R1= R2 = (CH2)5] were afforded in excellent enantioselectivities (up to 99 % ee) with up to 99 % yield.
Research on Chemical Intermediates published new progress about 5153-73-1. 5153-73-1 belongs to nitriles-buliding-blocks, auxiliary class Nitrile,Alkenyl,Nitro Compound,Benzene, name is (E)-4-(2-Nitrovinyl)benzonitrile, and the molecular formula is C9H6N2O2, SDS of cas: 5153-73-1.
