Herein, we report a multi-component reaction (MCRs) to synthesise a range of 3-phenyl-5-(bromomethyl)isoxazoles analogues using DMF/water mixture as solvent, providing desired products in good to excellent yields. The reaction efficiently involves the 1,3-dipolar cycloaddition reaction between propargyl bromide and in situ-generated α-chloro aldoximes. The protocol proceeded well under mild metal-free conditions and showed a tolerance for a wide range of substituents. Graphical abstract: [Figure not available: see fulltext.]
Product selectivity of thermal Buchner reaction of methyl 2-(3-arylisoxazol-5-yl)-2-diazoacetates with benzene, naphthalene and mesitylene, and ring-opening/closing reaction of products

Methyl 2-(3-arylisoxazol-5-yl)-2-diazoacetates were synthesized and the product selectivity of their thermal Buchner reaction with benzene, naphthalene and mesitylene was studied. The reaction of the isoxazolyl-substituted diazoacetates with benzene gave
