Regio- and stereo-chemical outcomes in the nucleophilic ring cleavage reactions of mono-epoxides derived from cis-1,2-dihydrocatechols

Banwell, Martin G.,Haddad, Najiba,Hudlicky, Tomas,Nugent, Thomas C.,Mackay, Maureen F.,Richards, Sharon L.

, p. 1779 - 1791 (2007/10/03)

Reactions of the mono-epoxy derivatives, 4-7, of the cis-1,2-dihydrocatechols 1 and 2 with various oxygen-, nitrogen-, carbon- and halogen-centred nucleophiles have been studied. In both direct and acid-catalysed processes these epoxides react exclusively
