Enantioselective [3+2] coupling of cyclic enamides with quinone monoimines was realised using a chiral phosphoric acid as a catalyst. This transformation allowed for the synthesis of highly enantioenriched polycyclic 2,3-dihydrobenzofurans (up to 99.9% ee). The absolute configuration of one product was determined by an X-ray crystal structural analysis. We also found a possible mechanism for this reaction.

supporting information, p. 552 - 559 (2013/05/08)
Some new 7-substituted-phenyl-3,4,8,9-tetrahydro-2H-pyridazino[1,6-a][1,3, 5]triazin-2-imine/one/thione derivatives were synthesized by a sequence of reactions starting from appropriate aryl hydrocarbons. The final compounds were screened for antihypertensive activities by non-invasive method using Tail Cuff method. All the test compounds showed significant antihypertensive activity; 7-(biphenyl-4-yl)-3,4,8,9-tetrahydro-2H-pyridazino[1,6-a][1,3,5]triazin-2-imine (4p) exhibited antihypertensive activity more than the reference standard drugs.
