Total synthesis of a cis-syn 2-carbomethoxypsoralen furan-side thymidine monoadduct
Kobertz, William R.,Essigmann, John M.
, p. 7101 - 7107 (1996)
The first total chemical synthesis of a cis-syn furan-side photoproduct between a psoralen derivative and thymidine is described. The key step in the synthesis was an intramolecular [2 + 2] photocycloaddition, which directed the stereochemical course of t
