Methyl (2′S,3′S)-3,4-O-(2′,3′-dimethoxybutane-2′,3′-diyl)-α-L-rhamnopyranoside: a glycosyl acceptor

Methyl (2′S,3′S)-3,4-O-(2′,3′-dimethoxy­butane-2′,3′-di­yl)-α-l-rhamnopyran­oside: a glycosyl acceptor

The title compound, C(13)H(24)O(7), is the product of the ketalization of methyl l-(+)-rhamnopyran-oside with 2,3-butane-dione. It crystallizes with two mol-ecules in the asymmetric unit, which are connected by O-H⋯O hydrogen bonds. The C-3,4 diequatorial hydroxy groups of the methyl l-(+)-rhamnopyran-oside were protected, leaving the C-2 hydroxy group free. The l-(+)-rhamnopyran-oside and 2',3...

Sensors 2002, 2, 23-34

This paper presents the development of a real-time microsensor-based monitoring system that can be used to detect and characterize volatile organic compounds in soil and groundwater. The system employs an array of polymer-based microsensors (chemiresistors) packaged in a waterproof housing that is designed to protect the sensor from harsh subsurface environments, including completely water-satu...

O-23: "Caring My Family Integrity"

Methyl 4-O-benzyl-α-l-rhamno­pyrano­side

In the title compound, C14H20O5, an inter-mediate in the synthesis of oligosaccharides, the glycosidic [H-C-O-C(H3)] torsion angle ϕH is 52.3° and the exo-cyclic [H-C-O-C(H2)] torsion angle θH is -11.7°. The hexa-pyran-ose ring has a chair conformation. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming chains propagating along [010]. Enclosed within the chains are R 3 (3)(1...
