We report a diversity-oriented synthesis of diverse drug-like polyheterocycles from Garner aldehyde derived 1-hydroxy-1,3-dihydroisobenzofuran 20 as a key intermediate. The oxonium-mediated nucleophilic addition of 20 in the presence of boron trifluoride-diethyl ether complex provided enantiopure 1,3-disubstituted 1,3-dihydroisobenzofurans through 1,3-asymmetric induction.

我们从加纳醛衍生的1-羟基-1,3-二氢异苯并呋喃20作为关键中间体,报道了多种药物样多杂环化合物的多元导向合成。在三氟化硼-乙醚复合物的存在下,由氧鎓介导的亲核加成20通过1,3-不对称诱导提供对映体纯的1,3-二取代的1,3-二氢异苯并呋喃。20的进一步多样化允许非药物选择性合成类似药物的多杂环化合物,包括3-取代的异苯并呋喃-1(3 H)-one,2,3-二氢-1 H-异吲哚-1-酮和3,4-二取代的二氢异喹啉酮环系统。 多样性导向的合成-加纳醛-异苯并呋喃-异吲哚-异喹啉
