, p. 2103 - 2108 (1994)
Stereospecific synthesis of Conduramine-F4 and Conduritol-F has been achieved by fully stereospecific cyloaddition of singlet oxygen to cyclohexadiene ketal 1 followed by reductive extrusion of one oxygen atom. The obtained monoepoxide 3 has be

A fully diastereoselective total synthesis of the lycorenine-type Amaryllidaceae alkaloid (±)-clivonine (19) is reported via a route that employs for the first time a biomimetic ring-switch from a lycorine-type progenitor, thereby corroborating experimentally the biogenetic hypothesis first expounded for these compounds by Barton in 1960.
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
