Synthesis of psoralens and analogues.
This review presents briefly the various classical syntheses of psoralens and angelicins which generally start from preformed suitably substituted coumarin or benzofuran derivatives. However, the discovery of the photocyclo-C-4 addition of psoralens to pyrimidine bases prompted new developments in this area. In particular, improved synthesis of psoralens and substituted angelicins, and synthesis of new analogues such as furochromenes, pyridopsoralens, pyrano benzopyrandiones, dioxinocoumarins and aza-psoralens were described recently. This review focuses on the chemical syntheses of these various compounds.
