Regioselective syntheses of 3-aminomethyl-5-substituted isoxazoles: A facile and chemoselective reduction of azide to amino by sodium borohydride using 1,3-propanedithiol as a catalyst
A series of isoxazole azides were reduced selectively to isoxazole amines in quantitative yield by sodium borohydride using 1,3-propanedithiol as a catalyst.
