complex serves as the catalyst for the high‐yielding and completely regioselective and asymmetric hydrogenation of substituted indolizines and 1,2,3‐triazolo‐[1,5‐a]pyridines. This method should provide ready access to bicyclic products bearing an N‐bridgehead, a motif appearing in 25–30 % of all naturally occurring alkaloids.
