to the mono MEM protected compound 8b. Dehydration of the tertiary alcohol using methanesulfonyl chloride-triethylamine-D M A P and treatment of the resulting product with lithium in liquid ammonia afforded 10. The diazoester of 10 was subjected to intramolecular cyclopropanation using a soluble copper complex to obtain 12. Cleavage of the MEM ether, dehydration of the tertiary alcohol followed by reductive
描述了由(R,R)-酒石酸合成(IR)-菊酸。二醇8被转化为单MEM保护的化合物8b。使用甲磺酰氯-三乙胺-D MAP对叔醇进行脱水,并用液氨中的锂处理生成的产物,得到10。使用可溶性铜络合物将10的重氮酯进行分子内环丙烷化,得到12。裂解MEM醚,叔醇脱水,然后在液体氨中用锂还原裂解,得到标题化合物。
