Thiourea-catalyzed aminolysis of N-acyl homoserine lactones.
Thiourea catalysts accelerate aminolysis of N-acyl homoserine lactones (AHLs), molecules integral to bacterial quorum sensing. The catalysts afford rate enhancement of up to 10 times the control in CD(3)CN. Mild catalysis in other polar aprotic solvents is still observed, while the activity is attenuated in polar protic solvents.
متن کاملKinetics and mechanism of the aminolysis of aryl N-ethyl thiocarbamates in acetonitrile.
The aminolysis of aryl N-ethyl thiocarbamates (EtNHC(=O)SC(6)H(4)Z) with benzylamines (XC(6)H(4)CN(2)NH(2)) in acetonitrile at 30.0 degrees C is investigated. The rates are faster than the corresponding values for aryl N-phenyl thiocarbamates (PhNHC(=O)SC(6)H(4)Z), reflecting a stronger push to expel the leaving group by EtNH than the PhNH nonleaving group in a concerted process. The negative r...
متن کاملAminolysis of an N-Diazeniumdiolated Amidine as an Approach to Diazeniumdiolated Ammonia
Recent theoretical studies have suggested that the parent diazeniumdiolate ion, H2N-N(O)═NO(-) ("diazeniumdiolated ammonia"), might be stable enough to be isolated and that it could potentially serve as a uniquely advantageous prodrug form of bioactive nitroxyl (HNO). Here, we report on an attempt to isolate its O(2)-benzylated derivative by aminolysis of the C═N bond in PhC(NH2)═N-N(O)═NOBn. T...
متن کاملAntibody-catalyzed aminolysis of a chloropyrimidine derivative.
We have generated antibody FTB8E9 by immunization with the designed hapten to catalyze the aminolysis reaction of a chloropyrimidine derivative.
متن کاملAminolysis of Dicationic Ruthenium Thiophene Complexes
Dicationic sandwich complexes containing thiophene, 2-methylthiophene7 2,5-dimethylthiophene, and tetramethylthiophene react with ammonia to give salts of the formula [(ring)Ru(SC4R4NH2)lX where ring = CsMe6 or cymene. The thiophene, 2-methylthiophene, and 2,5-dimethylthiophene complexes undergo C-S cleavage to give iminium-thiolato derivatives. In the case of the 2,5-dimethylthiophene complex,...
