TL;DR: Inulin, the polydisperse reserve polyfructose from plants such as Cichorium intybus (chicory), has been chemically modified several ways to obtain industrially important biodegradable compounds and its differences from starch and cellulose chemistry are described.
169 citations
TL;DR: The medium and long chain carbamoylated inulins showed a good to very good reduction of the interfacial tension which makes these biopolymers interesting in the field of biodegradable surface active agents.
97 citations
TL;DR: In this article, 2,5-Difunctionalised 3,3-dimethylpiperidines were prepared by addition of nucleophiles to piperideinium salts, formed by electrophile-induced cyclisation of γ,δ-unsaturated imines with N-bromosuccinimide in alcoholic medium.
9 citations
TL;DR: In this paper, the reaction of N -substituted 4-methyl-2-pyrrolidinones, carrying not less than two chlorine atoms on the C(3 and C(6) carbons afforded with alkaline methoxide in methanol, under mild conditions, was studied.

TL;DR: In this article, a short pathway involving dehydrohalogenation of α,γ,γ-trichloro-β-iminoesters was described, which opened the way to a number of previously unknown functionalised anthranilates.
5 citations
TL;DR: In this article, α-Chloro acylphosphonates and α,α-α′-dichloro bisacylphosphonsates were prepared in situ by chlorination using sulfuryl chloride using a hydrogen peroxide-sodium bicarbonate system.

TL;DR: In this article, α-Chloro acylphosphonates and α,α-α′-dichloro bisacylphosphonsates were prepared in situ by chlorination using sulfuryl chloride using a hydrogen peroxide-sodium bicarbonate system.
Abstract: α-Chloro acylphosphonates and α,α′-dichloro bisacylphosphonates were prepared in situ by chlorination of acylphosphonates and bisacylphosphonates, respectively, using sulfuryl chloride. Subsequently, they were cleaved to the corresponding α-chlorinated or α,α′-dichlorinated (di)carboxylic acids with a hydrogen peroxide–sodium bicarbonate system. Performing the cleavage with an alcohol or an amine yielded the corresponding α-chlorinated esters and α-chlorinated amides, respectively.
