Convenient Synthesis of 2-pyridyl thioglycosides

Heterocyclic thioglycosides in carbohydrate research: Synthesis of thiophene thioglycosides

A novel synthesis of thiophene thioglycosides is carried out via a one-pot reaction of sodium thiophenethiolates with α-halogeno sugars. The sodium thiophenethiolate salts were prepared using sodium cyanoethylene thiolate salts. The structures of the reaction products were established on the basis of their elemental analysis and spectral data (IR, ¹H NMR, MS, and ¹³C NMR).

Pyrimidine non-nucleoside analogs: A direct synthesis of a novel class of N-substituted amino and N-sulfonamide derivatives of pyrimidines

A convenient method for the regioselective synthesis of pyrimidine non-nucleoside analogs was developed. This study reports a novel and efficient method for the synthesis of a new type of N-substituted amino methylsulfanylpyrimidines and the corresponding pyrazolo[3,4-d]pyrimidines. This series of compounds was designed through the reaction of dimethyl N-cyanodithioiminocarbonate with 2-cyano-N'-(thiophen-2-yl-, furan-2-yl- and pyridin-4-ylmethylene)acetohydrazide and N'-(2-cyanoacetyl)arylsulfonohydrazides. The scope and limitation of the method are demonstrated. The antibacterial and antifungal activities of the synthesized compounds were also evaluated.
