Reactions of (Z)-3-aryl-3-chloropropenals with nucleophiles: stereoselective formation of (E)-vinylogous esters, (E)-vinylogous amides, and vinamidinium salts
The highly stereoselective conversions of (Z)-3-aryl-3-chloropropenals to (E)-3-alkoxy-3-arylpropenals, to (E)-3-aryl-3-morphorlinopropenals, and to vinamidinium salts are reported. The stereochemical assignments were based on 2D-NMR experiments.
