一般描述

p-Tolyl isothiocyanate reacts with 6-hydroxy-2,4,5-triaminopyrimidine or with 4,5,6-triaminopyrimidine in DMF and triethylamine to yield 2,4-diamino-5-(p-tolylthioureido)aminopyrimidin-6-one and 4,6-diamino-5-(tolylthioureido)aminopyrimidine, respectively.

应用

p-Tolyl isothiocyanate has been used:
  • in the preparation of 6-[1-amino-3-(p-tolyl)-thiourea]-2-ethylbenzo[de]isoquinoline-1,3-dione
  • as capping agent to cap the N-terminal ends of polypeptides

Methods for direct synthesis of N-(purin-8-yl)arylamines were investigated. N-(Purin-8-yl)arylamines are adducts from reaction of electrophilic metabolites of arylamines with DNA and have not been readily available by direct synthesis. Ability to generate significant quantities of this class of DNA adduct

The synthesis and isolation of the first stable C-B-N-substituted borinium [MesBNiPr2][B(C6F5)4] (2) is described. Compound 2 was shown to react with isothiocyanate and carbodiimides, effecting B-C insertion to afford nitrilium (4) and borenium amidinate salts, respectively. The borinium cation [MesBNiPr2]+

Despite promising anti-cancer properties in vitro, all titanium-based pharmaceuticals have failed in vivo. Likewise, no target-specific positron emission tomography (PET) tracer based on the radionuclide 45Ti has been developed, notwithstanding its excellent PET imaging properties. In this contribution, we present
