Two unusual modes of dimerization of 2-alkyl-6-methyl-4H-1,3-thiazin-4-ones were observed; one gave the linearly combined dimers (3) and the other led to the novel spiro-compound (4); the structure of one of the spiro-compounds (4a) was confirmed by X-ray crystallography.
观察到两种不同的2-烷基-6-甲基-4 H -1,3-噻嗪-4-酮二聚体的异常模式;一个给出了线性组合的二聚体(3),另一个给出了新颖的螺环化合物(4)。通过X-射线晶体学确认螺旋化合物(4a)之一的结构。
