描述了在BF 3中心点OEt 2存在下，N-叔丁烷亚磺酰基α-亚氨基酯与包括活化和非活化二烯的不同二烯的非对映选择性氮杂-Diels-桤木（aza-DA）反应。非对映选择性高达99%，观察到无环未活化的二烯。通过X射线衍射分析，确定了两种氮杂-DA产物的绝对构型。(c)2007爱思唯尔有限公司保留所有权利。
Diastereoselective aza-Diels-Alder (aza-DA) reactions of an N-tert-butanesulfinyl alpha-imino ester with different dienes including activated and non-activated dienes in the presence of BF3 center dot OEt2 are described. Diastereoselectivities up to 99% were observed for acyclic unactivated dienes. The absolute configurations of two aza-DA products have been solved by X-ray analysis. (c) 2007 Elsevier Ltd.
