Synthesis of 3,5-Disubstituted Isoxazoles via Cope-Type Hydroamination of 1,3-Dialkynes
摘要:
An efficient method for the synthesis of 3,5-disubstituted Isoxazoles is described. The reactions of 1,3-dialkynes with hydroxylamine proceeded smoothly in DMSO under mild reaction conditions to produce 3,5-disubstituted isoxazoles In satisfactory to excellent yields.
