Various Baylis–Hillman–derived new N-allylated 2-nitroiminoimidazolidine analogs were efficiently prepared using potassium carbonate as base. Simple workup procedure, excellent yields, and mild reaction conditions are the salient features of this method. All the synthesized compounds are screened for their larvicidal activity on fourth instar mosquito larvae, Culex quinquefasciatus.

Herein, a facile and efficient method for the preparation of allyl amides from the aldehyde of Baylis-Hillman adducts has been developed using a hydroxylamine/methanol system under a catalyst-free condition. The effects of solvents and temperature on the reaction and substituents on the phenyl ring have been examined. This method is best demonstrated by its advantages such as operational simplicity, moderate to excellent yields, short reaction time, and simple reaction procedure. Most importantly, the reaction proceeds smoothly in the absence of a catalyst and an external oxidant.

A series of deep eutectic solvents (DESs) based on choline chloride were prepared and used in the Morita-Baylis-Hillman (M-B-H) reaction. Research showed that the composite solvent (1ChCl/2Gly DES-H2O) is a very effective solvent media for all
Cl-H2O: An efficient and versatile solvent system for the DABCO-catalyzed Morita-Baylis-Hillman reaction

, p. 32839 - 32845 (2015/04/27)
An efficient and versatile solvent-catalyst system, [HyEtPy]Cl-H2O-DABCO, has been developed and used in the Morita-Baylis-Hillman reaction. Under the mild reaction conditions, Morita-Baylis-Hillman proceeds very quickly and efficiently. This protocol has notable advantages such as eco-friendliness, ease of work-up and reuse of ionic liquid conveniently, which could help reduce disposal costs and contribute to the development of a new solvent-catalyst system for use in green and continuous chemical processes.

Visible light irradiation of N-bromosuccinimide serves as an effective means to convert methyl 2-(azidomethyl)-3-arylpropenoates and 2-(azidomethyl)-3-arylacrylonitriles to the corresponding iminyl radicals via ?±-hydrogen abstraction and subsequent extrusion of dinitrogen. Thus formed iminyl radicals then undergo intramolecular ortho attack on the aryl ring, affording methyl quin-oline-3-carboxylates and quinoline-3-carbonitriles respectively.

This study presents the synthesis of 14 new 1,4-disubstituted piperazine derivatives from allyl bromides of Baylis-Hillman adduct and 4,4-disubstituted benzhydryl piperazines. All the synthesized compounds were further screened for in vitro ACE inhibitor and antimicrobial activities. Among the synthesized piperazine derivatives, compound 12h showed moderate ACE inhibitor activity as compared to the standard, angiotensin-converting enzyme inhibitor (Sigma). The kinetic data (K m, K i and V max values) of enzyme inhibition for compound 12h and ACE inhibitor standard were also determined. Similarly, all compounds were screened against different bacterial strains. Compounds 12a, 12b, 12d, 12h and 12i showed excellent to moderate activity against various tested bacterial strains. Compounds 12b and 12i showed broad spectrum of antibacterial activity against Pseudomonas aeruginosa, Staphylococcus aureus, S. aureus MLS 16, Escherichia coli, Bacillus subtilis and Klebsiella planticola, while compounds 12a, 12d and 12i showed promising activity against P. aeruginosa (MIC value of 8.96 μM), S. aureus (MIC value of 42.2 μM) and S. aureus MLS 16 (MIC value of 81.3 μM), respectively. The remaining compounds showed activity at a concentration of >491 μM.
