pharmaceuticals and agrochemicals. Herein, we disclose a straightforward synthesis of sulfinylated spiro[5.5]trienones proceeding via an unprecedented BF3·Et2O-promoted spirocyclization of biaryl ynones. The availability of relatively inexpensive BF3·Et2O to carry out transformations on a bulk scale along with its further application towards the synthesis of dibenzocyclohepten-5-ones delivers a unique opportunity
亚磺酰基是用于开发合成新药物和农用
化学品的有价值的结构部分。在此,我们公开了一种亚磺酰化螺[5.5]
三烯酮的直接合成方法,该合成通过前所未有的BF 3 ·Et 2 O-促进联芳基炔酮的螺环化进行。相对便宜的 BF 3 ·Et 2 O 的可用性可用于大规模规模的转化,及其在
二苯并环庚烯-5-酮合成中的进一步应用,为其在各种合成方向上的应用提供了独特的机会。
