The reaction of 3-mercapto-6-methyl-1, 2, 4-triazin-5 (2H)-one 1 with dimethyl 2a and trimethyl phosphite 3a at 100 C in absence of solvent yields the dimeric product 4 and while the alkylated products 5 and 6 are obtained for reaction with 3a. Methylation of 1 by methyl iodide gives alkylated product 5. Reaction of 1 with diethyl 2b and triethyl phosphite 3b by the same previous conditions yie...
We report that the binding of phosphite dianion to orotidine 5'-monophosphate decarboxylase (OMPDC) results in an 80 000-fold increase in kcat/Km for decarboxylation of the truncated substrate, 1-(beta-d-erythrofuranosyl)orotic acid (EO), which lacks a 5'-phosphodianion moiety. The intrinsic binding energy (IBE) of phosphite dianion in the transition state is 7.8 kcal/mol, which represents a ve...
An enantioselective dearomatization of isoquinolines has been developed using chiral anion-binding catalysis. This transformation, catalyzed by a simple and easy to prepare tert-leucine-based thiourea derivative, makes use of silyl phosphite as a nucleophile and generates cyclic α-aminophosphonates. This is the first time asymmetric anion-binding catalysis has been applied to the synthesis of α...
The synthesis, characterisation and catalytic behaviour of ruthenium indenylidene complexes bearing an N-heterocyclic carbene and triisopropylphosphite are described.
Carbonyl compounds react with organozinc reagents in the presence of diphenyl phosphite to give the corresponding olefins. A variety of 1,3-dienes and unsaturated esters were obtained in moderate to excellent yields under mild conditions.
Crystals of glycine phosphite G l y H 3 P 0 3 (abbreviated as GPI ) belong to the low-symmetry representatives of hydrogen-bonded crystals. At room temperature the unit cell of this compound is monoclinic (space group P21 /a) and contains four formula units [1]. The crystal structure is characterised by the presence of infinite chains of hydrogen-bonded phosphite anions that are directed along ...
The asymmetric unit of the title triangulo-triruthenium compound, [Ru(3)(C(25)H(22)As(2))(C(18)H(15)O(3)P)(CO)(9)], contains two crystallographically independent but similar mol-ecules. The bis-(diphenyl-arsino)methane ligand bridges an Ru-Ru bond and the monodentate phosphite ligand bonds to the third Ru atom. Both the phosphite and arsine ligands are equatorial with respect to the Ru(3) trian...
deprotection of phosphate, phosphate, and sulfite esters by silica chloride is described. silica chloride is a mild, selective, and effective reagent for cleavage of benzyl and t-butyl esters of the above compounds.
Three new linear benzene-fused bis(tetrathiafulvalene) compounds (1-3) were easily synthesized by one-step phosphite-induced cross-coupling reactions; a solution processed organic field-effect transistor based on 2 shows high mobility of 0.02 cm2/Vs.
