摘要:
The synthesis of syn-photodimer from 1,4-dihydropyridine without 4-aryl was studied, and its single crystal was obtained (C22H302O8, M-r = 450.48). It crystallizes in monoclinic, space group P2(1)/c with a = 11.937(2), b = 20.913(4), c = 9.763(2) angstrom, beta = 108.46(3)degrees, V = 2311.9(g) A(3), Z = 4, D-c = 1.294 g/cm(3), F(000) = 960, mu = 0.099 mm(-1), R = 0.0640 and wR = 0.1464 for 4077 unique reflections with 1599 observed ones (I > 2 sigma(I)). It is shown that the whole molecular structure of the title compound is a twist-boat conformation, and the two double bonds have a trend of potential intramolecular reaction under high-energy irradiation.
