Synthesis and Investigation of a Hindered, Chiral, Bicyclic Guanidine

Chiral amidines and guanidines have potential as enantioselective catalysts for reactions of nitroalkanes, through formation of hydrogen-bonded complexes with nitronate anions.With this in mind, the bicyclic guanidine 9 was synthesized from amino-alcohol

(4S,8S)-4,8-Bis(diphenylmethyl)-1,5,7-triazabicyclodec-5-ene; a Hindered, Chiral, Bicyclic Guanidine Base with Effective C2-Symmetry

The title compound 5 is prepared from L-methionine and investigated by computational, NMR spectroscopic and other techniques; the results indicate that the N/NH groups of 5 and its conjugate acid occupy hindered, chiral environments due to the disposition of the bulky diphenylmethyl substituents.
