	Process for the preparation of ribofuranose derivatives - Patent 6891036
		It is therefore subject of the present invention a process for the preparation of ribofuranose derivatives of formula(I): ##STR7##
		Further subject of this invention are the ribofuranose derivatives of formula (I): ##STR11##
		The mixture is stirred for 1 hour then slowly cooled down to 20° C. It is filtered under vacuum and the panel is washed with 10.38 Kg of toluene and with 6 Kg of hexane.

		Toyocamycin and some analogues have shown potent antitumor activities; however, none of them could be used clinically primarily owing to their cytotoxicity to normal human cells.
		In order to overcome the weakness of these nucleoside analogues, substitution of a variety of modified sugars for the ribofuranose was explored in our laboratories with expectation that certain sugar-modified toyocamycin analogues may be selectively cytotoxic to cancer cells.
		In this article, we report synthesis and cytotoxicity of 4´-C- and 5´-C-substituted toyocamycins, which were prepared via the condensations of 4-C- and 5-C-substituted ribofuranose derivatives 11, 12, 13, 20, 21, and 26 with the silylated form of 4-amino-6-bromo-5-cyanopyrrolo[2,3-d]pyrimidine (27) and subsequent debromination and debenzoylation.

	Herbicidal ribofuranose derivatives - Patent 5683963 (Site not responding. Last check: 2007-10-18)
		The present invention relates to herbicidal ribofuranose derivatives, particularly hydantocidin derivatives, compositions comprising said derivatives and methods of use.
		This invention relates to herbicidal ribofuranose derivatives, and particularly to hydantocidin derivatives, compositions comprising said derivatives and methods of treating weeds utilizing the application of said derivatives to a locus where control is desired.
		It has now been discovered that certain novel ribofuranose derivatives have good herbicidal and plant growth regulating activity when applied either pre or post emergence, but particularly post emergence and when used against annual and perennial grasses and broad leaf weeds.
