Dr. NO: Rhodium‐catalyzed intramolecular CH insertion with diazocompounds, which are tethered by alkoxyamines, afforded 1,5‐ and the rare 1,7‐insertion products (see scheme; Bn=benzyl). The resulting NO tether is unaffected under the CH insertion reaction conditions and it can be readily cleaved or transformed into various functionalities. The reduction of the NO moiety controls acyclic stereochemistry
博士Ñ ø:铑催化的分子内Ç ħ插入与diazocompounds,这是由烷氧基胺系留,得到1,5-和稀有1,7-插入的产品(参见方案; BN =苄基)。所得到的N- Ô系绳是C下不受影响 ħ插入反应条件,并可以很容易地切割或转化为各种功能。所述N个的还原 O部分控制无环的立体化学。
