A new general protocol for synthesis of fused 1,2,3-dithiazoles by the reaction of cyclic oximes with S2Cl2 and pyridine in acetonitrile has been developed. The target 1,2,3-dithiazoles fused with various carbocycles, such as indene, naphthalenone, cyclohexadienone, cyclopentadiene, and benzoannulene, were selectively obtained in low to high yields. In most cases, the hetero ring-closure was accompanied
已开发出通过环肟与 S2Cl2 和吡啶在乙腈中反应合成稠合 1,2,3-二噻唑的新通用方案。目标1,2,3-二噻唑与各种碳环稠合,如茚、萘酮、环己二烯酮、环戊二烯和苯并环烯,选择性地以低收率到高收率获得。在大多数情况下,杂环闭合伴随着碳环部分的氯化。使用萘酮衍生物,发现了一种新的二噻唑重排(15→13),其特征是二噻唑环从 α-位到 β-位(相对于酮基)出乎意料地移动。4-chloro-5H-naphtho[1,2-d][1,2,3]dithiazol-5-one 13 的分子结构由单晶 X 射线衍射证实。
