Reaction of a novel chiral N-acryloylhydrazide with various nitrile oxides proceeded smoothly to afford the cycloadduct with high diastereoselectivity (99:1). The auxiliary can be easily removed from the cycloadducts under mild conditions.
新型手性N-丙烯酰肼与各种腈氧化物的反应进行得很顺利,从而得到具有高非对映选择性(99:1)的环加合物。在温和的条件下,可以轻松地从环加合物中除去辅助剂。
