, (2018/06/23)
The invention relates to the fields of organic synthesis and pharmacy, and particularly relates to a synthesis method of a drug for treating diabetes. The synthesis method comprises the following steps of (1), hydrolyzing 2-cyanophenyl tert-butyl sulfide to produce o-carbamoylphenyl tert-butyl sulfide; (2), oxidizing the o-carbamoylphenyl tert-butyl sulfide to produce o-carbamoylphenyl tert-butylsulfoxide; (3), enabling the o-carbamoylphenyl tert-butyl sulfoxide to generate an intramolecular multicomponent reaction with phenyl isocyanide to produce 2-(aniline)-4H-benzo[e][1,3]thiazin-4-one. The synthesis method is simple, convenient and environmentally friendly, is easy to operate and suitable for industrialized production, and is low in cost and high in yield; synthesis raw materials areeasily obtained, and the atom economy is achieved.

Direct reaction of isocyanides with some sulfenic-acid-generating sulfoxides led to the effective formation of the corresponding thiocarbamic acid S-esters in good to high yields. A multicomponent reaction involving isocyanide, sulfoxide, and a suitable nucleophile has also been developed, providing ready access to a diverse range of sulfur-containing compounds, including isothioureas, carbonimidothioic acid esters, and carboximidothioic acid esters.
