Notes:
When bioxazolones 2 are treated at high temperature with 5-amino-4,5-dihydrotriazoles, 3, the corresponding triazolylmethyl-5(4H)-oxazolones 4 and 5 are produced by dissociation of 2 into oxazolonyl radicals and reaction of these with 3, followed by transfer a hydrogen or morpholinyl radical. Products 4 and 5 ar also formed starting form 3 and 5(4H)-oxazolones 1, which are oxidized during the reaction to the corresponding bioxazolone 2, In this case, besides products 4 and 5, the corresponding triazolymethyl-5(4H)-oxazolones 6 are also formed, presumably by nucleophilic attack of the anion of 1 on substrate 3.
