Rhodium-catalyzed transannulation of 1,2,3-triazoles and ring-opening reactions of epoxides is described. A number of 3,4-dihydro-2H-1,4-oxazines are obtained in moderate yields probably involving generation of α-imino rhodium(II) carbene species.
متن کاملA QSAR study on 5-HT6 receptor antagonists: the 3,4-dihydro-2H- benzo[1,4]oxazines
This study has provided a rational approach for the development of new 3,4-dihydro-2H-benzo[1,4]oxazine derivatives as potential 5-HT6 antagonists. The descriptors identified in CP-MLR analysis have highlighted the role of atomic van der Waals volume in terms of BEHv6, path/walk ratio 3 and 4Randic shape index (PW3 and PW4), number of rotatable bonds (RBN) and superpendentic index (SPI) to expl...
