5-Oxodihydroisoxazoles react with thiocarbonyl chlorides to afford
N-thioacylisoxazol-5(2H)-ones which lose carbon
dioxide under photochemical conditions and undergo intramolecular
cyclisation of the iminocarbene to afford thiazoles. However, in some
cases loss of carbon dioxide is accompanied by loss of sulfur, giving
1,3-oxazin-6-ones.
