Rezumat:

Novel masked 2-arylacroleins I (R1 = 2-MeC6H4, 4-MeC6H4, 2-FC6H4, 4-FC6H4, 2-ClC6H4, 4-MeOC6H4, MeS, 5-Me-thien-2-yl) have been developed to serve as 2-arylpropenal synthons. Formal 1,2-addns. onto the aldehyde moieties of I (R = 4-MeC6H4) provided the corresponding 2-substituted allyl alcs. II (R1 = Me, Ph) for the first time. Conversion of I (R1 = 4-MeC6H4, 2-ClC6H4) to imines allowed for the prepn. of 1,2-disubstituted allyl amines III (R1 = 4-MeC6H4; R2 = Me; R3 = MeO; R1 = 2-ClC6H4; R2 = Me; R3 = H; R1 = 4-MeC6H4; R2 = n-Bu; R3 = MeO).
