Ten differently substituted ynamines 1a-j react with five nitrile oxides 3a-e to give the 5-aminoisoxazoles 4a-z.The stannyl-substituted ynamine 1k 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.
