Description_x000D_ General description_x000D_ In the laboratory, levoglucosenone (1,6-anhydro-3,4-dideoxy-β-D-glycero-hex-3-enopyranos-2-ulose, LGO) can be synthesized from H3PO4-treated, Kraft waste-paper via pyrolysis. It can also be synthesized from the acid-treated cellulose and paper via pyrolysis. It undergoes Michael-addition reaction with diethyl malonate, ethyl cyanoacetate, 2-nitropropane and 2-methylcyclohexanone in the presence of various catalysts to afford 4-substituted levoglucosenone derivatives having the D-erythro configuration. Magnetic super acid (SO4-2/TiO2-Fe3O4) mediated pyrolysis of cellulose and poplar wood has been proposed for the selective synthesis of LGO._x000D_ Application_x000D_ Levoglucosenone may be used in the synthesis of the following:_x000D_ • various deoxy, keto and branched-chain sugars_x000D_ • 4-thio and 4-substituted sugar derivatives_x000D_ • natural stereoisomer of serricornin_x000D_ Packaging_x000D_ 10 mg in glass bottle
