annulation of benzoic acids with nitroalkenes was disclosed to afford a wide range of 3,4-disubstituted isochroman-1-ones with excellent regioselectivity and high catalytic efficiency. Both aromatic and aliphatic nitroalkenes participated in this cyclization reaction successfully. The synthetic value of 3,4-disubstituted isochroman-1-ones was proven by a series of derivatizations. Furthermore, a reliable
研究表明,Rh(III) 催化的苯甲酸与硝基烯烃的环化反应可生成多种 3,4-二取代异色满-1-酮,具有优异的区域选择性和高催化效率。芳香族和脂肪族硝基烯烃均成功参与了该环化反应。通过一系列衍生化实验证明了3,4-二取代异色满-1-酮的合成价值。此外,在实验研究和相关先例的基础上概述了可靠的机制。
