NOVEL DENTAL COMPOSITES SYSTEMS AND METHODS OF MAKING THE SAME AND USING SAME

The invention includes a composition comprising a vinyl sulfone monomer, a thiol monomer, and optionally an isocyanate monomer. The invention further includes a composition comprising a composition comprising the tetra(2-mercapto)silane (SiTSH) monomer an

A new photoclick reaction strategy: Photo-induced catalysis of the thiol-Michael addition via a caged primary amine

The utilization of 2-(2-nitrophenyl)propyloxycarbonyl (NPPOC) as a photolabile primary amine cage enables the thiol-Michael 'click' reaction to be photo-triggered. The photolabile amine exhibits efficient catalytic activity upon UV irradiation and is shown to initiate the photopolymerization of tetrathiol and diacrylate comonomers via Michael addition.

Synthesis of four glycosides of a disaccharide fragment representing the terminus of the O-polysaccharide of Vibrio cholerae O:1, serotype Inaba, bearing aglycons suitable for linking to proteins

Methyl 4-azido-3-O-benzyl-4,6-dideoxy-α-D-mannopyranoside was converted into the crystalline 2-(trimethylsilyl)ethyl 4-azido-2-O-benzoyl-3-O-benzyl-4,6-dideoxy-α-D-mannopyranoside. Debenzoylation of the latter, followed by glycosylation of the resulting 2-hydroxy derivative with 2-O-acetyl-4-azido-4,6-dideoxy-α-D-mannopyranosyl chloride, gave the 2-(trimethylsilyl)ethyl glycoside of the corresponding disaccharide (8). Deacetylation of 8, followed by reduction of the resulting 4-azido-2-hydroxy derivative with H2S, gave the corresponding amine 10. The latter was treated with 4-O-benzyl-3-deoxy-L-glycero-tetronic acid to give, after debenzylation and acetylation, the fully protected 2-(trimethylsilyl)ethyl α-glycoside of the disaccharide fragment of the O-PS of Vibrio cholerae O:1, serotype Inaba (13). Compound 13 was transformed into the corresponding 1-trichloroacetimidate which was treated, separately, with methyl 6-hydroxyhexanoate and 2-(2-methoxycarbonylethylthio)ethanol, to give two analogs of 13 possessing a differing linkage arm, namely the methyl esters 16 and 17. Each of 16 and 17 was treated with aqueous sodium hydroxide, followed by a cation-exchange resin, to give the two corresponding carboxylic acids (19 and 22). Alternately, treatment of 16 and 17 with hydrazine hydrate gave the acid hydrazides 20 and 23.

Polymerizable thioester synergists

There are disclosed polymerizable thioester synergists which have utility in enhancing the antioxidative activity of phenolic and amine stabilizers. The invention is also concerned with the thioesters themselves, their use in oxidizable organics, their combination with polymerizable and/or conventional antioxidants, and with polymers which contain these thioesters as physical admixtures or segmeric units of the polymer.
