As part of an ongoing project aimed at developing vaccine candidates against Cryptococcus neoformans the preparation of tri- and tetrasaccharide thioglycoside building blocks, to be used in construction of structurally defined part structures of C. neoformans GXM capsular polysaccharide, was investigated. Using a naphthalenylmethyl (NAP) ether as a temporary protecting group and trichloroacetim...

The title donor, ethyl 2-acetamido-4,6-di-O-benzyl-2,3-N,O-carbonyl-2-deoxy-1-thio-beta-D-glycopyranoside, is shown to be an excellent glycosyl donor giving immediate and efficient access to variant GlcNAc-containing oligosaccharides.

The mol-ecular structure of the title compound, C(18)H(23)N(3)S, shows it to be a derivative of an amino-thio-phenol possessing a tetra-methyl-guanidine group with a localized C=N double bond of 1.304 (2) Å and a protected thiol functional group as an S-benzyl thio-ether. The two aromatic ring planes make a dihedral angle of 67.69 (6)°.

The title compound, C(9)H(11)N(3)OS, was prepared by the reaction of 3-methoxy-benzaldehyde and thio-semicarbazide. The benzyl-idene ring and the thio-semicarbazone fragment are slightly twisted, making a dihedral angle of 14.1 (1)°. A weak intra-molecular N-H⋯N hydrogen bond may influence the conformation of the mol-ecule. Inter-molecular N-H⋯S hydrogen bonds build up a three-dimensional network.

In the title mol-ecule, C(22)H(19)NOS(2), the piperidine ring adopts an envelope conformation with the benzyl substituent in an equatorial position. Each of the olefinic double bonds has an E configuration. The dihedral angle between the two thio-phene rings is 1.55 (18)°. The thio-phene rings form angles of 72.21 (14) and 73.43 (14)° with the phenyl ring. Both thio-phene rings are disordered o...

The title complex, [Cu(C22H19N2O3S2)2], was obtained from the reaction between (Z)-methyl 2-(5-benzyl-imino-4-benzyl-carbamo-thioyl-3-oxo-thio-lan-2-yl-idene)acetate and Cu(NO3)2. The Cu(II) atom is tetra-coordinated by two N,S-bidentate ligands, forming a highly distorted tetra-hedral environment. The structure displays two intra-molecular N-H⋯O hydrogen bonds.

As part of an ongoing project aimed at identifying protective capsular polysaccharide epitopes for the development of vaccine candidates against the fungal pathogen Cryptococcus neoformans, the synthesis and glycosylation properties of a naphthalenylmethyl (NAP) orthogonally protected trisaccharide thioglycoside, a common building block for construction of serotype B and C capsular polysacchari...

The crystal structure of the dinuclear arene ruthenium title complex, [Ru2(C6H5OS)(C7H7S)2(C10H14)2]BF4, shows the two Ru(II) atoms to be bridged by two benzyl-thio-pheno-late units and one 4-hy-droxy-thio-pheno-late unit, with the remaining three coordination sites of each Ru(II) atom being occupied by p-cymene ligands, completing the typical piano-stool coordination geometry. The BF4 (-) coun...

The reaction of thio-phene-3-carboxaldehyde and perfluoro-benzyl-triphenyl-phospho-nium bromide in the presence of sodium hydride gave the title compound, C(12)H(5)F(5)S, in 70% yield. The thiophene and perfluorophenyl groups form a dihedral angle of 5.4 (2)°. The structure is characterized by a head-to-tail organization in a columnar arrangement due to π-π inter-actions between the thio-phene ...
