synthetic approach, using a chiral Reissert adduct, was too problematic to be pursued further. In the second successful approach, the authors took advantage of the stereoselective epoxidation of a 1,2-dihydroquinoline bearing an Evans' chiral auxiliary at N-1.
描述了从喹啉开始的 (-)-(R)-舒马尼罗的十二步合成。第一种合成方法,使用手性 Reissert 加合物,问题太大,无法进一步研究。在第二种成功的方法中,作者利用了在 N-1 处带有 Evans 手性助剂的 1,2-二氢喹啉的立体选择性环氧化。
