However, catalytic asymmetric approaches have been rarely developed. Here, a redox deracemization technology is adopted to address the catalytic asymmetric synthesis. A broad range of α-aryl substituted 1,3-dihydroisobenzofurans are effectively deracemized in high efficiency with excellent ee. α-Alkynyl substituted ethers were also compatible with the deracemization technology.
手性α-取代的 1,3-二氢异苯并呋喃是许多生物活性天然产物和合成药物的关键支架。然而,很少开发催化不对称方法。在这里,采用氧化还原去消旋技术来解决催化不对称合成问题。广泛的α-芳基取代的 1,3-二氢异苯并呋喃可以高效地去消旋,并具有优异的ee。α-炔基取代醚也与去消旋技术兼容。
