The Diels–Alder reaction of juglone with various styrenes in the presence of 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) was promoted by B(OAc)3 at room temperature. The reaction proceeded smoothly and gave the products in a good yield and with excellent regioselectivity. This strategy was applied to the total syntheses of tetrangulol and anhydrolandomycinone.
在室温下,B(OAc)3促进了在2,3-二氯-5,6-二氰基苯并醌(DDQ)存在下,朱古龙与各种苯乙烯的Diels-Alder反应。反应进行顺利,并以良好的产率和良好的区域选择性得到产物。该策略适用于丁香酚和脱水地霉素的总合成。
