  Synthesis and Anticholinesterase Activity of 3-{[4-Methyl-3-(4-methylpiperazin-1-yl)]pent-1-en-1-yl}-4H-chromen-4-ones

  摘要：

  A procedure has been developed and optimized for the synthesis of 3-{[4-methyl-3-(4-methylpiperazin-1-yl)]pent-1-en-1-yl}-4H-chromen-4-ones (as dihydrochlorides) by an unusual version of the Morita-Baylis-Hillman reaction. A number of the title compounds with various substituents in the chromene fragment and their deamination products have been synthesized, and their inhibitory activity against butyrylcholinesterase has been studied.

  The effect of electronic properties of substituents in the reactants on the [4+2]-cycloaddition of 3-vinyl-chromen-4-ones (dienes) and N-vinylpyrrolidines (dienophiles) has been studied. The conditions determining the formation of 4,4a-dihydroxanthones or benzophenones as the major products have been found. The aromatization of 4,4a-dihydroxanthones via pyran ring opening has been interpreted by quantum

  We report a new environmentally-benign, convenient and facile methodology for the synthesis of new series of 3(4-oxo-4H-chromen-3-yl)acrylic acid hydrazides derivatives designed by exploring the molecular hybridization approach between isoniazide and 3(4-oxo-4H-chromen-3-yl)acrylic acids by using EDCl/HOBt under ultrasound irradiation in very short reaction time. Utilization of easy reaction conditions, isolation and purification makes this manipulation very interesting from an economic perspective. (C) 2010 Elsevier B.V. All rights reserved.
