A general and efficient lactonization method of readily available 2-alkynylbenzoates affording biologically important isochromenones has been realized via a solely BF3·Et2O-mediated 6-endo-dig cyclization process under mild condition
Synthesis of 3-arylisocoumarins, including thunberginols A and B, unsymmetrical 3,4-disubstituted isocoumarins, and 3-ylidenephthalides via iodolactonization of methyl 2-ynylbenzoates or the corresponding carboxylic acids

3-Aryl-4-iodoisocoumarins, which were readily and efficiently prepared by regioselective iodolactonization of methyl 2-ynylbenzoates or the corresponding carboxylic acids, were used as precursors either to 3-arylisocoumarins, including naturally-occurring
Organomercury Mediated Synthesis of Isocoumarins
Nagarajan, A.,Balasubramanian, Tiruvenkat R.
, p. 917 - 919 (2007/10/02)
A facile and convenient synthesis of isocoumarins via an organomercurial route is reported.The synthesis involves reaction of methyl 2-alkynbenzoates with mercuric acetate to give the corresponding isocoumarin mercurials which serve as intermediates to afford the appropriate isocoumarins having substituents as Cl,I,Br,COCH3 etc.
