Yamada, Shinji; Yamagami, Kaoru; Oaku, Saki published the artcile< [2+2] Photodimerization of (E)-styrylthiazoles through cation-π-controlled preorientation>, SDS of cas: 1003-32-3, the main research area is diphenyl thiazolyl cyclobutane preparation diastereoselective regioselective; styrylthiazole photodimerization.
Cation-π-controlled preorientation of (E)-styrylthiazoles RCH=CHC6H5 (R = 1,3-thiazol-2-yl, 1,3-thiazol-4-yl, 1,3-thiazol-5-yl) was performed in both solution and solid phases. Irradiation of (E)-styrylthiazoles in the presence of HCl produced synHT dimers I (R = 1,3-thiazol-2-yl, 1,3-thiazol-4-yl) in good selectivities, while little selectivity was observed without HCl. X-ray structures for the HCl salts of (E)-styrylthiazoles showed a head-to-tail arrangement through cation-π interactions between the two neighboring mols. Irradiation of these HCl salts produced synHT dimers I in excellent yields.
