The total synthesis of (+)-valienamine and (−)-1-epi-valienamine was concisely accomplished from readily available d-glucose via a highly diastereoselective amination of chiral benzylic ether using chlorosulfonyl isocyanate, intramolecular olefin metathesis, and diastereoselective reduction of cyclic enone using l-Selectride as the key steps.
(+)-戊烯胺和(-)-1-表-戊烯胺的总合成是由易得的d-葡萄糖通过使用氯磺酰基异氰酸酯进行手性苄基醚的高度非对映选择性胺化,分子内烯烃复分解和非对映选择性还原环而完成使用l -Selectride作为关键步骤。
