A general approach towards synthesis of 5-hydroxyalkylbutan-4-olides from D-mannitol has been described. The approach has been used successfully for total synthesis of (-)-muricatacin, an anti-tumour natural product. Other related natural and unnatur

Aromatic electrophilic substitution reactions such as alkylation, acylation, benzoylation, and sulfonylation were studied in the presence of a catalytic amount of Cu(OTf) 2 and Sn(OTf) 2 . Cu(OTf) 2 was very efficient for alkylation, acylation, and b
