摘要: An efficient palladium-catalyzed [2 + 1]cycloaddition between ynamides and norbornenes or norbornadienes is reported. Both phosphapalla- dacycles palladium/secondary phosphine oxide catalytic systems were found to be competent for the transformation allowing preparation of ami- nomethylenecyclopropanes. The reaction showed general applicability various functionalized bicyclo[2.2.1]hept-2-enes ynamides. A chiral phosphapalladacycle was tested carry out this in an enantioselective fashion.
