摘要
(Chemical Equation Presented) Bridging the gap: Configurationally stable ethano-bridged Tröger bases have been prepared in a single step by the direct rhodium(II)-catalyzed reaction of methano-bridged Tröger bases and diazo esters (see scheme). The process is general, enantiospecific, diastereoselective (with introduction of a new quaternary carbon center), and regioselective. © 2011 Wiley-VCH Verlag GmbH & Co. KGaA.
