An Efficient Synthesis of Bicyclic Amidines by Intramolecular Cyclization

Kumagai, Naoya,Matsunaga, Shigeki,Shibasaki, Masakatsu

, p. 478 - 482 (2007/10/03)

A real step-saver! In a one-step procedure for the synthesis of bicyclic amidines, the azido group is used directly as the nucleophile in the ring-forming reaction. Many functionalized and chiral bicyclic amidines were synthesized in good yield under mild reaction conditions.
