Condensation reactions of various nucleophiles with 3-formylchromone

3-Formylchromones 1 are condensed with 1-(2,4-difluorophenyl-2-[1,2,4] tnazol-4-yl)ethanone in acetic anhydride to afford 3-[3-(2,4-difluoro-phenyl)-3- oxo-2-[1,2,4]triazol-4-yl)propenyl]chromon-4-ones 2. 3-Formylchromone 1 when heated with benzo[d]isoxazol-3-yl-acetic acid in dry pyridine yield 3-(2-benzo[d]isoxazol-3-yl-vinyl)chromon-4-ones 3. Further, 3-formylchromone 1 on heating with N-methylpiperizine in ethanol give 1-(2-hydroxyphenyl)-3-(4- methyl-piperazin-1-yl)propenones 4.

Synthesis, anti-bacterial, anti-asthmatic and anti-diabetic activities of novel N-substituted-2-(benzo[d]isoxazol-3-ylmethyl)-1H-benzimidazoles

(Chemical Equation Presented) Synthesis of a series of novel class of N-substituted-2-(benzo[d]isoxazol-3-ylmethyl)-1H-benzimidazoles (4) by the condensation of o-phenylenediamine (1) with benzo[d]isoxazol-3-yl-acetic acid (2) and subsequent reactions with different types of electrophiles have been reported. Some compounds exhibited promising anti-bacterial activity against Salmonella typhimurium, however poor activity against Staphylococcus aureus. The compound 4t was found to have high activity even at 1 mug/ml compared to Cephalexin against S. aureus. The biological activity against PDE-IV for potential anti-asthmatic effect and against DP-IV and PTP-1B for potential anti-diabetic effects was disappointing.

Facile preparation of protected benzylic and heteroarylmethyl amines via room temperature Curtius rearrangement

A step-wise, room temperature procedure for acyl azide formation and the subsequent Curtius rearrangement of phenyl and heteroaryl acetic acids is described. We have developed a protocol for room temperature Curtius rearrangement in MeOH or CHCl3 that provides an improvement over standard conditions, avoiding the use of additives or heat. This room temperature optimization of the Curtius rearrangement prevents the formation of side products often observed with benzylic acids, allowing access to a variety of benzylic and heteroarylmethyl amines.

Process for the preparation of 1,2-benzisoxazole-3-acetic acid

The present invention provides a process for preparing 1,2-benzisoxazole-3-acetic acid, comprising the step of reacting 4-hydroxy-coumarin with hydroxyl-amine in the presence of a base. The present invention further provides a process for preparing a salt of benzisoxazole methane sulfonic acid, comprising the steps of 1) sulfonating 1,2-benzisoxazole-3-acetic acid using chlorosulfonic acid in a solvent mixture comprising methylene chloride and sodium hydroxide; and 2) isolating the salt of benzisoxazole methane sulfonic acid.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.4865-84-3, you can also check out more blogs about4865-84-3
