inhibitor of trehalase, an enzyme that cleaves the reserve carbohydrates of many insects. We describe a short and efficient synthesis of trehazolin (2) and trehazolamine (5) that mimics its hypothetical biosynthesis. Starting molecule for the synthesis of trehazolamine (5) is glucose from which three chiral centers are conserved during the reaction sequence. The remaining two chiral centers of trehazolamine
Trehazolin(2)是海藻糖酶的一种特异抑制剂,海藻糖酶可切割许多昆虫的储备碳水化合物。我们描述了模仿其假设的生物合成的Trehazolin(2)和Trehazolamine(5)的短而有效的合成。合成Trehazolamine(5)的起始分子是葡萄糖,在反应过程中从中保守了三个手性中心。在酮肟醚16的还原环化反应和肟醚18的还原反应中,立体选择性地形成了Trehazolamine(5)的其余两个手性中心。在从15开始的8个步骤中,trehazolamine(5)的总收率为22%。 (2)由海藻胺(5)遵循已知程序,可在3个步骤中达到63%。
