KGaA, Weinheim Phthalide is an important scaffold found in several biologically active compounds. Therefore, effective methods for the synthesis of phthalides are strongly desired. Herein, we describe the metal-free synthesis of 3-substituted phthalides by the reductive hydroiodination of 2-alkynylbenzoates through an I 2 /PPh 3 /H 2 O-triggered cascade reaction. A variety of 3-substituted phthalides were synthesized in excellent yields by a one-pot reaction involving four processes: desilylation, hydroiodination, cyclization, and reduction.抄録:英語フィールド
