On January 30, 1997, Nilsson, Kurt G. I. published a patent.SDS of cas: 130539-43-4 The title of the patent was Method of producing derivatives of β-D-glucosyl-1,4-N-acetyl-β-D-glucose. And the patent contained the following:
Disclosed is a method of producing a compound which contains the G1cβ1-4G1cN structure involving reacting ≥1 donor substance G1cβOR where R is an organic group, and ≥1 acceptor substance which is a glucopyranosamino derivative having the formula G1cNR”-R”’, wherein NR” is an azido, 2-N-acetyl-, 2-N-phthalimido, or an organic group bound to the 2-N-group of glucosamine, wherein R”’ is a glycosidically bound fluoro or is an O-, C-, N- or S-glycosidically bound aliphatic or aromatic compound, with the optional proviso that if NR” is NHAc then R”’ is not OH and if NR” is not NHAc then R”’ may be OH, in the presence of Bullera singularis or an enzyme commission (E.C.) group 3.2 glycosidase of essentially the same structure as an E.C. group 3.2 glucosidase obtained from B. singularis to form the G1cβ1-4G1cN derivative; and optionally isolating the compound which contains the G1cβ1-4G1cN structure. The experimental process involved the reaction of Ethyl 2-deoxy-2-(1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl)-1-thio-beta-D-glucopyranoside(cas: 130539-43-4).SDS of cas: 130539-43-4
