Lipo-Chitooligosaccharidic Nodulation Factors: Synthesis and Agricultural Perspectives
Autor: Jean-Marie Beau
Publikováno v: CHIMIA, Vol 65, Iss 1-2 (2011)
Lipo-chitooligosaccharidic nodulation (Nod) factors produced by rhizobia are a class of signalling molecules that induce a symbiotic association between legumes and soil bacteria rhizobia leading to the formation of the nitrogen-fixing root nodule. T

From Chitin to α-Glycosides of N -Acetylglucosamine Using Catalytic Copper Triflate in a Heated Sealed-Vessel Reactor
Autor: Stéphanie Norsikian, Jean-Marie Beau, Dany Frem, Dominique Urban
Publikováno v: European Journal of Organic Chemistry. 2017:5094-5101
The selective preparation of α-glycosides of GlcNAc has been accomplished using a direct copper(II) triflate-catalyzed glycosylation between the α-D-glucosamine pentaacetate, readily available from chitin, and a range of alcohol acceptors. The α-s

Publikováno v: European Journal of Organic Chemistry. 2017:3355-3361
Regioselective differentiation of the hydroxy groups of mono- and oligosaccharide substrates is necessary to form building blocks that can be used for synthetic transformations. In this paper, we show that iron(III) chloride hexahydrate catalyses the
