category: Tetrahydropyrans, Career opportunities within science and technology are seeing unprecedented growth across the world, and those who study chemistry or another natural science at university now have increasingly better career prospects. 28244-94-2, C21H26O9S. A document type is Patent, introducing its new discovery.
Field of the invention relates to sugar compounds, in particular relates to a method for preparing 2, 3, 4, 6-tetra-O-benzyl-D-pyran semi-acetyllactosyl method. Galactose in acetic anhydride and catalyst, 2-mercaptobenzothiazole preparation of benzothiazole base sulfo- under the action of acetyl galactose. Benzothiazole base sulfo- acetyl galactose in potassium hydroxide and under the action of benzyl chloride benzothiazole prepared base sulfo- four phenmethyls semi-lactose. Benzothiazole base sulfo- four phenmethyls semi-lactose in role-bromosuccinimide N preparation of 2, 3, 4, 6-tetra-O-benzyl-D-pyran semi-lactose. The method of the invention by a three-step reaction method for synthesizing 2, 3, 4, 6-tetra-O-benzyl-D-pyran semi-lactose, effectively improve the purity and yield of the product; the operation is simple, easy availability of raw materials, saving the operation cost and material.
