本文描述了邻醌类化合物的Diels-Alder反应，可合成各种取代苯并吡喃。在低温条件下，与-取代的邻醌类化合物的反应具有很高的非对映选择性。
The Diels-Alder reactions of o-quinone methides generated from OBOC-salicylic aldehydes and alcohols are described, allowing for the synthesis of various substituted benzopyrans. The low temperatures employed for this procedure enable high diastereoselectivity in reactions with beta-substituted o-quinone methides.
