Rapid Assembly of Functionalized Hydrodibenzofurans via Semipinacol Rearrangements
摘要:
A distinct strategy via unprecedented semipinacol rearrangements for the synthesis of functionalized hydrodibenzofurans is reported. The versatile reactivity of benzofuran-3-one as a building block enabled the convergent coupling of simple starting materials and, thus, allowed for the facile variation of R group and the construction of hydrodibenzofurans with fused rings.
