highly stereocontrolled preparation, on a large scale, of two new Wieland−Miescher-type diketones is described. The approach centers on a diastereoselective Diels−Alder reaction using a new enantiomerically pure sulfinylquinone. Mechanistic investigations of this cycloaddition on several dienes are described.
本文描述了一种高效且高度立体控制的大规模制备两种新的Wieland-Miescher型二酮的方法。该方法集中于使用新对映体纯的亚磺酰基醌的非对映选择性Diels-Alder反应。描述了在几种二烯上进行这种环加成反应的机理研究。
