Described are novel crystalline pivaloyl furanoses and methods of crystallizing the pivaloyl furanoses. These compounds are useful as intermediates in the synthesis of compounds such as the deoxyjirimycins and nojirimycins and are particularly useful as intermediates for production on a multi-kg scale. Particular crystalline compounds include 1,2,3,6-tetrapivaloyl-α-D-galactofuranose, 1,2,3,6-tetrapivaloyl-α-L-altrofuranose, and 5-azido-5-deoxy-1,2,3,6-tetrapivaloyl-α-D-galactofuranose.
本文描述了新型结晶式戊酰基呋喃糖以及结晶戊酰基呋喃糖的方法。这些化合物可用作合成脱氧吉利霉素和诺吉霉素等化合物的中间体,并且在多千克级别的生产中特别有用。特定的结晶化合物包括1,2,3,6-四戊酰基-α-D-半乳糖呋喃糖、1,2,3,6-四戊酰基-α-L-阿尔卓糖呋喃糖和5-叠氮基-5-脱氧-1,2,3,6-四戊酰基-α-D-半乳糖呋喃糖。
