Enantiomeric [4+2] cycloadduct-based 2-oxazolidinones (3a and4a), newly derived from 9,10-dimethylanthracene and 2-oxazolone, serve as the most effective Evans' auxiliaries so far developed in diastereoselective alkylations and Diels-Alder reactions.
对映体[4 + 2]基于环加合物的2-恶唑烷酮(3a和4a),是新衍生自9,10-二甲基蒽和2-恶唑酮的化合物,是迄今为止在非对映选择性烷基化和Diels-Alder反应中开发的最有效的Evans助剂。 。
