Mastachi-Loza, Salvador published the artcileSynthesis of 4,5,6,7-tetrahydrobenzoxazol-2-ones by a highly regioselective Diels-Alder cycloaddition of exo-oxazolidin-2-one dienes with chalcones, Recommanded Product: 2,3-Dimethoxybenzaldehyde, the main research area is tetrahydro benzoxazolone regioselective diastereoselective preparation; exo oxazolidinone diene chalcone Diels Alder cycloaddition.
The synthesis of 4,5,6,7-tetrahydrobenzoxazol-2-ones I [R1 = C6H5, 4-MeOC6H4, 2-thienyl, etc.; R2 = C6H5, 4-MeOC6H4, 4-ClC6H4; stereo = R or S] and II [R1 = C6H5, 4-MeSC6H4, 4-MeOC6H4, 2,4-di-ClC6H3; R3 = C6H5, 4-MeC6H4, 4-ClC6H4, 3-MeOC6H4] was reported. They were obtained in moderate to good yields by a highly regio- and stereoselective Diels-Alder cycloaddition of N-substituted exo-oxazolidin-2-one dienes with chalcones or bis-chalcones as dienophiles.
