T3P - A Benign Desulfurating Reagent in the Synthesis of Isothiocyanates

A number of alkyl, aryl and bifunctional isothiocyanates are obtained in moderate to high yields (41-94%) in a two-step, one-pot reaction of the parent primary amines or their salts with carbon disulfide, followed by reaction of the thus formed dithiocarbamates with T3P (propane phosphonic acid anhydride) as a new and efficient desulfurating agent.

p-Aromatic Isothiocyanates: Synthesis and Anti Plant Pathogen Activity

In this study, a series of p-aromatic isothiocyanates are prepared by reacting p-aromatic amines with carbon disulphide and further treating with molecular iodine to yield corresponding isothiocyanate derivatives. The structures of newly synthesized compounds are confirmed by IR, NMR, and MS data. Activity of the products against plant pathogenic fungi and bacteria is tested and the structure-activity relationship is approached. p-Nitrophenyl isothiocyanate most efficiently inhibits Rhizoctonia solani and Erwinia carotovora. The order of seven aromatic isothiocyanates antifungicidal activity is following: p-nitrophenyl > p-methoxyphenyl > p-chlorophenyl > p-methylphenyl > p-ethylphenyl > phenyl > p-fluorophenyl. For antibacterial activity, the order was p-nitrophenyl > p-chlorophenyl > p-methylphenyl > p-ethylphenyl > p-fluorophenyl > phenyl > p-methoxyphenyl. The present study indicates that some of the compounds exhibit promising antimicrobial activity and can be used as an alternative to the traditional synthetic fungicides for controlling R. solani and E. carotovora.

Na2S2O8-mediated efficient synthesis of isothiocyanates from primary amines in water

We have developed two green, practical, and efficient procedures, including a one-pot one, to synthesize isothiocyanates from amines and carbon disulfide via desulfurization with sodium persulfate. Water is used as the solvent. Basic conditions are necessary for good chemoselectivity for isothiocyanates. Structurally diverse linear and branched alkyl amines and aryl amines are readily converted to isothiocyanates by the two procedures in satisfactory yields. Halogens, benzylic C-H bonds, methylthio, nitro, ester, alkenyl, electron-rich or -deficient (hetero)aryls, acetylenyl, and even phenolic and alcoholic hydroxyls are well tolerated. The one-pot procedure in water can also be used to realize the preparation of chiral isothiocyanates from chiral amines, and the modification of bioactive structures with free amino groups. In large-scale preparation, simple and practical purification procedures independent of column chromatography are developed.

Synthesis and biological evaluation of dihydroisoquinoline-2(1H)- carbothioamide derivatives as TRPV1 antagonists

TRPV1 receptor is an important analgesia target. Its antagonists are expected to prevent pain perception by blocking the receptor directly. In this letter, eight dihydroisoquinoline-2(1H)-carbothioamide derivatives were designed and synthesized as TRPV1 antagonists. The benzene ring was modified with different substitutional groups. Preliminary biological tests suggested that the new compounds exhibited TRPV1 antagonist activity and different analgesia effects, some of which were promising as analgesia drugs.
