An unusual addition of enamines to chromone‐substituted acrylic acid is an efficient and versatile method of synthesis of allylamine derivatives. The reaction is catalyzed by amines and is highly likely of Morita–Baylis–Hillman‐type. The described compounds show combined moderate inhibitory action on BChE and antagonism towards NMDA receptors

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.

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.
