An in situ generated samarium complex as a practical catalyst for the efficient intramolecular hydroamination of non-activated alkenes
摘要:
Mixing Sml(2) and NaN(TMS)(2) generates in situ an efficient catalyst that promotes the intramolecular hychoamination of non-activated olefins. A wide range of aminoolefins can be cyclised smoothly using this simple protocol. Mechanistic studies led to the identification of the putative active catalyst. (c) 2008 Elsevier Ltd.

The intramolecularhydroamination of a large variety of non-activated alkenes can be efficiently catalysed by small amounts of lithium bases, providing smoothly and in high yields the corresponding five- and six-membered ring heterocycles. Fused and bridged bicyclic amines, of varying ring sizes, can be readily prepared either by a sequential hydroamination process or by a tandem, double addition reaction
