Preparation method of beta-amino acrylonitrile compounds

The invention discloses a preparation method of beta-amino acrylonitrile compounds. Beta-aminocyanoacrylate represented by formula I reacts in a solvent under the action of a catalyst to obtain the beta-aminoacrylonitrile compounds represented by formula II; and in the formulas, R is a C1-C12 alkyl group, a halogenated C1-C12 alkyl group, a C3-C12 cycloalkyl group, a C2-C12 alkenyl group, a C2-C12 alkynyl group, an aryl group, a substituted aryl group, a benzyl group or a substituted benzyl group, and R is hydrogen, halogen, a hydroxyl group, an amino group, a cyano group, a nitro group,a C1-C12 alkyl group or a halogenated C1-C12 alkyl group. The method has the characteristics of good stereoselectivity, high yield, simplicity preparation of the raw material beta-aminocyanoacrylate,and great practical value.

Synthesis of fluorinated 2-phenyl-4-quinolones from pyrrole-2,3-diones

A series of substituted 2-phenyl-4-quinolones 8-11 have been synthesized in good yields via flash vacuum thermolysis (FVT) of 1-aryl-4-cyano-5-phenylpyrrole-2,3-diones 7a-e and 1-aryl-4-methoxycarbonyl-5-phenylpyrrole-2,3-diones 7f-j. The pyrrolediones 7

E/Z Photoisomerization of 3-Amino-3-phenylprop-2-enenitriles

The E/Z photoisomerization of 3-phenyl-3-(N-substituted amino)- and 3-phenyl-3-(N,N-disubstituted amino)-prop-2-enenitriles was investigated by means of u.v. and 13C n.m.r. spectroscopy.Informative results on the mechanism of the reaction produced by direct irradiation of 3-anilino-3-phenylprop-2-enenitrile were obtained from the different effects of quenchers and heavy atoms.Neither the heavy atoms nor the quenchers had any effect on direct photoisomerisation, which involves only the singlet state, by-passing the triplet state.
