A bicyclic analogue of β- d -mannopyranose with nitrogen atoms replacing the ring and glycosidic oxygen atoms has been prepared in a single step from 5-O-mesyl- d -mannofuranose by a process that likely involves double displacement and an epoxide in

Here we describe a new and simple method for preparing alkyl monolayers on silicon, which consists of mechanically scribing oxide-coated silicon while it is wet with 1-alkenes or 1-alkynes (neat or in inert solvents) under ambient conditions. X-ray p

Reaction of 3-amino-1-propanol with 5-bromo-5-deoxy-d-xylose in aqueous solution gives anomeric hexahydropyrido[2,1-b][1,3]oxazine-7,8,9-triols 2α and 2β. When this reaction was monitored by 1H NMR, it was observed that the α-anomer formed 20 time

Bicyclic azasugar analogues of D-xylose containing a glycosidic heteroatom have been prepared and characterized by X-ray crystallography and NMR spectroscopy. Compounds in which the glycosidic heteroatom is N (substituted with H or CH3), O, and S hav

Bicyclic diazasugar analogues of L-arabinose and D-ribose have been prepared and characterized by x-ray crystallography and NMR spectroscopy. The crystalline arabinose analogue is the β-anomer in the ring-flipped 1C4 conformation (7), but in D2O sol

This paper presents data on the 15N chemical shift tensor principal values in a series of 15N-enriched heterocycles. Compounds that are liquids at room temperature were frozen, and the principal va...
