Abstract: A novel method for the preparation of stavudine polymorphic form I and form II is described. 5?-acetate-2?,3?-diacetyl-5-methyluridine is reacted with catalytic amounts of sodium methoxide in a C1-C4 alcoholic solvent, resulting in crude stavudine form II. Crude stavudine form II can be converted into polymorphic stavudine form I by slurry at reflux in isopropanol, without isolating or purifying the crude stavudine form II.

Abstract: A window with built-in devices that senses carbon monoxide; powered only by the exterior daylight; that automatically opens by itself and sounds an alarm when a dangerous level of carbon monoxide is sensed to release the accumulated carbon monoxide and let the clean air with fresh oxygen enter the contaminated area to prevent or minimize poisoning and/or death of humans & animals without the need of any human physical action; the provided contacts can be connected to a private alarm station to alert the Fire & Police Departments to provide immediate assistance to the endangered humans & animals and protect the opened residence.

Abstract: A bedroom window that detects predetermined levels of carbon monoxide and automatically open by itself to save the occupants lives without any external electrical supply, replaceable alkaline batteries or any human action; this lifesaver window is self-contained, pre-assembled, solar-powered, environmentally friendly and able to open the window sash by itself to allow the CO to escape, to reduce CO concentration, to let the outside clean air to enter the room, to sound it's alarm, and to trigger the Fire & Police Private Central Station Alarm; it can be installed as new or as a replacement window in homes, hotels, hospitals, dormers or wherever humans or animals live; can be manufactured in different sizes and styles to accommodate any architectural design and furthermore it installation requires the same skills & tools needed to install a regular window without the need of other trades.

Abstract: A process for the preparation of ribavirin on an industrial scale is described which comprises the reaction of glycosylation of 3-substituted triazoles in the presence of a Lewis acid. Said process comprises: a) the reaction of a triazole of the formula ?with a protected ribofuranose of the formula b) the removal of the Pg groups and, optionally, the conversion into a carboxyamide group of the R2 group of the compound obtained of the formula ?DD/mac—01.07.02.

Abstract: A process for the preparation of L-ribavirin on an industrial scale is described which comprises the reaction of glycosylation of 3-substituted triazoles in the presence of a Lewis acid.

Abstract: A process is disclosed for manufacturing N-methyl-N-phenylaminoacrolein of formula (I) which comprises reacting N-methylformanilide and an alkyl vinyl ether of formula (III) wherein R is a C3–C4 alkyl, said process being characterized in that the reaction between N-methylformanilide and said alkyl vinyl ether of formula (III) is carried out in the presence of phosgene, diphosgene or triphosgene in a solvent selected from dioxane, acetonitrile and/or chlorobenzene.

Abstract: A process is disclosed for manufacturing N-methyl-N-phenylaminoacrolein of formula (I) 1

Abstract: A process for the preparation of L-ribavirin on an industrial scale is described which comprises the reaction of glycosylation of 3-substituted triazoles in the presence of a Lewis acid and of a solvent. Said process comprises: a) the reaction of a triazole of formula (I) with a protected L-ribofuranose of formula (II)b) the removal of the Pg groups and, optionally, the conversion into a carboxyamide group of the R2 group of the compound obtained of formula (III) to give L-ribavirin.
