Oximes aziridine ring

Vinyltriazolines are unique thermolysis leads to high yields of 1-vinylaziridines. This is true of fused-ring tetracyclic (Scheme 40)199,201 and tricyclic triazolines (Schemes 42 and 43)200 204 with vinylic substitution in the 1-position. 1-Vinyltriazoline with no substituents on the ring carbons furnishes 1-vinylaziridine without formation of pyrrolines.378 Thermal decomposition of vinyl azides in acrylic acid derivatives is a synthetic route for 2-substituted 1-vinylaziridines.470 Similarly, aziridine 1-oximes are the only products of thermolysis of triazoline 1-oximes.107... [Pg.330]

Lithium tetrahydridoaluminate Aziridine ring from oximes... [Pg.438]

The aziridine (23), which results from reduction of the oxime (22) with LiAlH4, gives dibenzo[6,/]thiepin (24) when treated with nitrous acid or when reduced catalytically (Pd-C), and with aqueous acid undergoes ring-contraction to the aldehyde (25) as shown. ... [Pg.550]
