摘要

以亚砜亚胺、异氰酸酯、醛和tms叠氮化物为原料，在甲醇中，在70℃条件下合成了亚砜亚胺基四氮唑。用磺酰咪胺(SIA)代替亚砜亚胺产生了相应的SIA基四唑。有趣的是，SIA也作为替代胺来完成相应的氨四唑作为副产物。

Synthesis of α-Sulfoximino Tetrazoles via Azido-Ugi Four-Component Reaction

The sulfoximine based tetrazoles have been synthesized via Azido-Ugi four component reactions of sulfoximines, isocyanides, aldehydes, and TMS-azide in MeOH at 70 ℃ in the presence of InCl3. Replacement of sulfoximine with sulfonimidamide (SIA) have delivered corresponding SIA based tetrazole. Interestingly, SIA is also acting as a surrogate amine to accomplish corresponding aminotetrazole as by-product.
