N-(omega-Bromoalkyl)dichlorothiophosphoramidates have been designed as a new class of reagent for the single-reagent-driven multistep preparation of 2-substituted thiazolines and 1,3-thiazines from aldoximes, nitriles, or carboxylic acids. A wide range of substrates both aromatic as well as aliphatic were investigated and found suitable for the developed protocol.

Thiazolines were synthesized in a one-pot reaction in excellent yield using a newly developed methodology. Ketonitriles were directly condensed with cysteamine (2-amino-thioalcohol) via microwave irradiation at 210°C for 10 minutes under solvent free conditions and without any solid support. All the compounds were characterized by 1H nmr, 13C nmr spectroscopy and elemental analyses.
使用一种新开发的方法,通过一锅反应以优异的产率合成了噻唑啉。在无溶剂条件下且无任何固体载体的情况下,通过在210°C微波辐射10分钟将酮腈与半胱胺(2-氨基-硫醇)直接缩合。所有化合物均通过1 H nmr,13 C nmr光谱和元素分析进行表征。
