Ring-closing-metathesis-based synthesis of annellated coumarins from 8-allylcoumarins
Schultze, Christiane,Schmidt, Bernd
, p. 2991 - 2998 (2018)
8-Allylcoumarins are conveniently accessible through a microwave-promoted tandem Claisen rearrangement/Wittig olefination/ cyclization sequence. They serve as a versatile platform for the annellation of five- to seven-membered rings using ring-closing ole
Zeolite-promoted Synthesis of Coumarins and Thiocoumarins

Acidic zeolites, especially faujasites, efficiently promote the intramolecular cyclization of aryl propynoates and propynethioates, which produces coumarins and thiocoumarins, usually in high yields. Comparison with homogeneous Lewis or Br?nsted acids and
Palladium-catalyzed intramolecular hydroarylation of 4-benzofuranyl alkynoates. Approach to angelicin derivatives
Kitamura, Tsugio,Otsubo, Kensuke
, p. 2978 - 2982 (2012/05/04)
Intramolecular hydroarylation of 4-benzofuranyl alkynoates using Pd(OAc)2 as catalyst took place selectively and efficiently, giving angular furocoumarin derivatives in high yields. The parent angelicin was obtained in 80% yield by this method.
