A short and efficient total synthesis of the naturally occurring coumarins siderin, kotanin, isokotanin A and desertorin C
Starting from methyl 2-hydroxy-4-methoxy-6-methyl-benzoate (6) and its regioisomeric dehydrodimers 7-9, readily available by an oxidative coupling reaction of 6, the naturally occurring coumarins siderin (1), kotanin (2), isokotanin A (3) and desertorin C (4) were synthesized in a novel and highly efficient three-step transformation. In the case of kotanin (2) both atropisomers were prepared from the pure atropisomers of 7.
