Chemistry is traditionally divided into organic and inorganic chemistry. Application In Synthesis of 2-Cyanoimino-1,3-thiazolidine, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent£¬Which mentioned a new discovery about 26364-65-8

A new sulfenylation reagent, 3-phenylsulfenyl-2-(N- cyanoimino)thiazolidine, and its optically active version

We have developed a new sulfenylation reagent, 3-phenylsulfenyl-2-(N- cyanoimino)thiazolidine 3, that is readily available and stable upon storage. Compound 3 easily reacts with amines or thiols to give the corresponding sulfenamides or asymmetrical disulfides in excellent yields. It was also found that the alpha-sulfenylation reaction of carbonyl compounds with 3 proceeds smoothly. Furthermore, optically active 4-diphenylmethyl derivative 4 was synthesized as an asymmetric sulfenylation reagent, which realized 96% e.e. upon alpha-sulfenylation of a cyclic beta-keto ester.

A Convenient and General Method for the Preparation of tert-Butoxycarbonylaminoalkanenitriles and Their Conversion to Mono-tert-butoxycarbonylalkanediamines

A new method is described for the synthesis of tert-butoxycarbonylaminoalkanenitriles 3 by dehydration of the corresponding carboxamides 2 (prepared in two steps from aminoalkanoic acids) in the presence of trifluoroacetic anhydride and triethylamine.N-Boc-aminoalkanenitriles 3 are easily converted to mono-N-Boc-alkanediamines 4 under mild conditions avoiding the cleavage of the N-protective group.The monoprotected alkanediamines 4 are useful tools in affinity chromatography.
