In relation with studies directed to the total synthesis of pseurotin A, conversion of α-hydroxy-β-diketones to the corresponding furan-3(2H)-ones have been successfully performed by a new method using K2CO3 in methanol. Cyclization of 7 yielded bullatenone (8).

伪神经素A的全合成的研究,已经通过使用
甲醇中的K 2 CO 3的新方法成功地进行了α-羟基-
β-二酮到相应的
呋喃-3(2H)-酮的转化。7的环化产生布地那通(8)。
