含金属沸石，特别是Sn-β，在左旋葡萄糖酮的选择性氧化中作为非常有效的多相催化剂，左旋葡萄糖酮被认为是用于生产高价值化学品的平台化学品，用于使用H2 O2作为氧化剂合成光学纯的γ-内酯（S）-γ-羟甲基-α，β-丁烯二酸（HBO）。使用Sn-β作为催化剂，在“一锅”级联反应中实现了高达75%的（S）-γ-羟甲基-α，β-丁烯二酸的产率。当Sn-β与酸性树脂如Amberlyst-15结合时，“两步”工艺的产率可高达90%。
Metal-containing zeolites, especially Sn-Beta, perform as very efficient heterogeneous catalysts in the selective oxidation of levoglucosenone, which is considered as a platform chemical for the production of highly-valuable chemicals, towards the synthesis of the optically pure gamma-lactone(S)-gamma-hydroxymethyl-alpha,beta-butenolide (HBO) using H2O2 as an oxidizing agent. Using Sn-Beta as a catalyst, yields up to 75% of (S)-gamma-hydroxymethyl-alpha,beta-butenolide are achieved in a "one-pot" cascade reaction. When Sn-Beta is combined with an acid resin, such as Amberlyst-15, the "two-step" process allows yields up to 90%.
