Zusammenfassung
Figure presented In this paper we describe a highly regioselective ring-opening metathesis-cross metathesis (ROM-CM) process between methyl N-Boc-7-azabicyclo[2.2.1]hept-2-en-1-carboxylate, a bridgehead-substituted 7-azanorbornene system, and electron-poor olefins. The reaction opens the way to the synthesis of interesting α-amino diacids and pyrrolizinone derivatives that incorporate quaternary stereocenters. © 2007 American Chemical Society.
