Organic-base-catalyzed synthesis of phthalides via highly regioselective intramolecular cyclization reaction
Kanazawa, Chikashi,Terada, Masahiro
, p. 933 - 935 (2007)
The organic-base-catalyzed 5-exo intramolecular cyclization reaction of o-alkynylbenzoic acid produces the corresponding phthalide regioselectively in good to excellent yields. The method provides a practical access to the phthalides, an important class o
Synthesis of isocoumarins: Rhenium complex-catalyzed cyclization of 2-ethynylbenzoic acids
Umeda, Rui,Yoshikawa, Shunya,Yamashita, Kouji,Nishiyama, Yutaka

When 2-ethynylbenzoic acids were treated with a catalytic amount of a rhenium complex, such as ReCl(CO)5, 6-endo cyclization of 2-ethynylbenzoic acids proceeded with a high selectivity to give the corresponding isocoumarins in moderate to good yields.
