Abstract: | C24H20N2O3, Pbc21, a = 11.338(4), b = 7.786(3), c = 44.381(6) Å, Dx = 1.29 Mg · m−3, V = 3.82053 · 10−27 m3. There are eight molecules in the unit cell (two molecules, A and B, in the asymmetric unit). The substitution of N (CMAP-Oxine) by CH(CMAB-Oxine) in the aldehyde participant of reactants creates differences both in intermolecular contacts and orientation phenomenons of ring planes. A high degree of selectivity of the substitution position for both compounds is given. The reactions to the synthesis of both compounds are difficult to agree upon with the characteristic feature of the Mannichreaction and corresponded more to the character of the electrophilic substitution of aromatics. |
