N3-Substituted derivatives of 2',3'-O-isopropylideneuridine (1) were synthesized and their pharmacological effects on the central nervous system (CNS) examined using mice. Methyl (2), ethyl (3), propyl (4), butyl (5), allyl (6), benzyl (7), o-, m-,p-xylyls (8, 9, 10), and α-phenylethyl (11) derivatives of 1 were administered to mice by intracerebroventricular (i.c.v.) injection for evaluating hypnotic activity, pentobarbital-induced sleep prolongation, and spontaneous activity as indices. Only 3 possessed hypnotic activity by i.c.v. injection at the dose of 2.0 μmol/mouse. Compounds 3, 4, and 10 significantly showed synergism with a barbiturate, indicating that the derivatives have some CNS depressant effects. Moreover, 3 and 4 caused decrease in the spontaneous activity of mice, even at low doses. The present study indicated that substitution by ethyl, propyl, and p-xylyl groups at the N3-position of 2',3'-O-isopropylideneuridine imparted the CNS depressant effects.

The regioselective palladium catalysed hydrostannylation of alkynes bearing a β-heteroatom affords mainly α-vinyltin(IV) compounds that are used as terminating species in palladium catalysed cyclisation-anion capture processes. The pharmacophore attached
General Method for the Preparation of N3- and O4-Substituted Uridine Derivatives by Phase-Transfer Reactions

A general method for regioselective introduction of a variety of protecting groups into the uracil residue of 1 has been developed by use of the phase-transfer reaction.Under such conditions, acyl groups such as benzoyl, p-toluyl, p-anisoyl, (2,2,2-trichl
