ortho-(Phenylpropioloxy)benzonitrile sulphide, generated in situ by thermal decarboxylation of the oxathiazolone (1), undergoes intramolecular 1,3-dipolar cycloaddition forming the chromenoisothiazole (4a); ortho-cinnamoylbenzonitrile sulphides also yield (4), together with nitrile, chromenoquinoline and amino-chromene by-products.
通过氧杂噻唑酮(1)的热脱羧原位生成的邻-(苯丙氧基)苯甲腈硫化物进行分子内的1,3-偶极环加成反应生成铬异噻唑(4a);邻-肉桂酰基苄腈硫化物也与腈,色酚喹啉和氨基色烯副产物一起产生(4)。
