P 58 Photoinduced template synthesis of cyclobutane-containing crown ether [Electronic resource] / I. G. Ovchinnikova, O. V. Fedorova, P. A. Slepukhin, G. L. Rusinov // Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya). - 2008. - Vol. 57, № 1. - P212-214 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: The photoinitiated [2+2]-cycloaddition of 1,5-bis[2-(3-phenyl-3-oxoprop-1-en-1-yl)phenoxy]-3-oxapentane in solution was studied. In the presence of potassium cations, the reaction is intramolecular and gives crown ether containing the ?-truxin-type cyclobutane fragment (anti, head-to-head) as the major product. \\\\Expert2\\nbo\\Russian Chemical Bulletin\\2008, 57 (1), 212.pdf |
