(Chemical Equation Presented) The enantioselective Bronsted acid catalyzed addition of methyleneaminopyrrolidine to N-Boc imines has been achieved in the presence of chiral phosphoric acids derived from 3,3′-di(phenanthryl)-H8-BINOL. The corresponding ami

A product study of the reaction between a number of aromatic amines substituted with widely different groups and paraformaldehyde in inert solvents was performed and found to yield 1,3,5-triaryl-1,3,5-hexahydrotriazines, 1,3,5,7-tetraaryl-1,3,5,7-tetrazocines and formaminals.It was not possible to correlate the product outcomes with the actual structure of the amine substrate.The X-ray diffraction structural determination of 1,3,5-tri-(t-butylphenyl)- (1b) and 1,3,5-tri-(m-fluorophenyl)-1,3,5-hexahydrotriazine (1c) showed the diaxial arrangement of the N-substituents.
