Bismuth(III) bromide in organic synthesis. A catalytic method for the allylation of tetrahydrofuranyl and tetrahydropyranyl ethers
摘要:
A bismuth bromide-catalyzed (10.0 mol %) multicomponent reaction involving the allylation of THF- and THP-ethers, followed by in situ derivatization with acetic anhydride to generate highly functionalized esters has been developed under solvent-free conditions. To the best of our knowledge, this is the first report of a catalytic procedure for the allylation of THF- and THP-ethers to yield ring-opened products. (C) 2010 Elsevier Ltd. All rights reserved.

A novel delivery system for drugs, and especially macromolecules such as proteins or oligonucleotides through biological membranes is provided, and specifically delivery of siRNA The delivery system comprises conjugation of the macromolecule drug to a moiety that enables effective passage through the membranes. Respectively, novel compounds and pharmaceutical compositions are provided, utilizing said delivery system. In one aspect of the invention, the compounds may be utilized in medical practice, for example, in delivery of siRNA or antisense oligonucleotides across biological membranes for the treatment of medical disorders.
