标题:Methods for synthesis of alpha-d-gal (1~>3) gal-containing oligosaccharides
发明人：BORNAGHI LAURENT; DEKANY GYULA; DRINNAN NICHOLAS BARRY; PAPAGEORGIOU JOHN; WEST MICHAEL LEO
摘要:This invention relates to reagents and methods for synthesis of biologically active di- and tri-saccharides comprising α-D-Gal(1→3)-D-Gal. In particular the invention provides novel reagents, intermediates and processes for the solution or solid phase synthesis of α-D-galactopyranosyl-(1→3)-D-galactose, and derivatives thereof. In one preferred embodiments the invention provides a protected monosaccharide building block of general formula (II): in which R 3 is methoxy or methyl; R 1 is H, benzoyl, pivaloyl, 4-chlorobenzoyl, acetyl, chloroacetyl, levulinoyl, 4-methylbenzoyl, benzyl, 3,4-methylenedioxybenzyl, 4-methoxybenzyl, 4-chlorobenzyl, 4-acetamidobenzyl, or 4-azidobenzyl; and R 2 is H, Fmoc, benzoyl, pivaloyl, 4-chlorobenzoyl, acetyl, chloroacetyl, levulinoyl, 4-methylbenzoyl, benzyl, 3,4-methylenedioxybenzyl, 4-methoxybenzyl, 4 -chlorobenzyl, 4-acetamidobenzyl, or 4-azidobenzyl.

标题 :Process for the synthesis of 5-(α-hydroxyalkyl) benzo[1,3]dioxols
发明人：BORZATTA VALERIO; BRANCALEONI DARIO
权利人:ENDURA SPA
摘要:The present invention regards a three-step process for the synthesis of 5-(alpha-hydroxyalkyl) benzo[1,3]dioxols. The process comprises: (i) the reaction of pyrocatechin (1,2-dihydroxybenzene) with a dihalo or di-alkoxyalkane, with the formation of a benzo[1,3]dioxol derivative; (ii) 5-selective catalytic acylation of the benzo[1,3]dioxol, with formation of a 5-alkanoylbenzo[1,3]dioxol and its subsequent (iii) reduction to 5-(alpha-hydroxyalkyl) benzo[1,3]dioxol. Also described are new benzodioxols obtainable using the above-mentioned process. The process of the invention is industrially simple and has low environmental impact; it allows to obtain in high yields derivatives of considerable interest, in particular for the perfumery industry, and in the sector of insecticides.

标 题 :Process for synthesis of 5-alkylbenzodioxoles
发明人：BORZATTA VALERIO; BRANCALEONI DARIO; BATTISTINI CHRISTIAN
权利人:ENDURA SPA
摘要:The following description refers to a new process for the synthesis of 5-alkylated benzo[1,3]dioxole, comprising the following steps in sequence: catalytic hydrogenation of 4-acylphenol; acylation; displacement catalysed by Lewis acids; treatment with an inorganic basic compound and hydrogen peroxide; reaction with alkyl dihalides or dialkoxyalkanes. n The process described herein, which yields 5-alkylbenzo[1,3]dioxoles, is economic and can be easily scaled up to industrial size.
