Convenient modular construction of medicinally important 5-acylamino-4,5-dihydroisoxazoles featuring four elements of diversity

An efficient modular approach toward medicinally important 5-acylamino-4,5-isoxazolines via the 1,3-dipolar cycloaddition reaction of nitrile oxides and MCR-derived enamide building blocks is described. This approach results in isoxazolines containing four elements of diversity utilizing two practically simple synthetic operations
