Here is reported the chemoselective opening of the amide bond on a Vince lactam derivative with amines, without the cleavage of the epoxide-moiety, getting five new epoxides. Also reported is the rearrangement of the epoxides into the respective five

A new family of isoxazolopyridobicyclooxacalix[4]arenes was obtained by reaction of dichloroisoxazolopyridines with phloroglucinol. X-ray crystallography and density functional calculations were used for their structural determination and evaluation

This article describes a new route to peptidosulfonamide. Our study shows how sulfinamides were first obtained via nucleophilic cleavage of 3,6‐dihydrothiazine‐1‐oxide system and how the products can be subjected to oxidation with m‐chloroper
