✦ Synopsis
Cycloadditions, 18. — 5‐Aminoisoxazoles by Cycloaddition of Nitrile Oxides to Ynamines
Ten differently substituted ynamines 1a–j react with five nitrile oxides 3a–e to give the 5‐aminoisoxazoles 4a–z. The stannyl‐substituted ynamine 1c furnishes the same compounds (e.g. 4a–d) by reaction with the hydroximoyl chlorides 2a–d. Two representatives of 4–b and p ‐ can be transformed into the corresponding 1‐azirine‐3‐carboxamides 6a and b.
