Addition of a propargylsilane moiety onto chiral cyclic of an allenic amino acid in the acyclic series; however, this isomerization did not take place with the cyclic α-amino ester iminium ions occurs with a high level of stereoselectivity intermolecularly as well as intramolecularly. This operation
also reflected in redox potentials. The furochlorophin 1 b oxidizes to its li cation radical at 0.47 V and reduces at -1.25 V to the anion radical (determined by cyclic voltammetry. versus Ag/AgCl, in CH,CI,). In comparison with etiochlorin I,1121 1 b is easier to oxidize as well as to reduce by abo
