Configurationally-stable ethano-Tröger bases are prepared in a single step via the direct Rh(II)-catalyzed reaction of methano-Tröger bases and diazo esters. The process is general, enantiospecific (ee up to 99%), diastereoselective (with a new quaternary carbon center introduction, dr up to 49:1) and regioselective.
