Abstract
The title compound N, N-dimethyl-1-ferrocenylethylaminehydrochloride [Fe(C5H5)(C5H4CHCH3N+H(CH3)2)Cl-] was synthesised by esterification of the corresponding alcohol, followed by substitution with HN(CH3)2 and by extracting HCl from CH2Cl2 probably associated with Fe in the substrate molecule. Its structure was first elucidated by X-ray analysis. By analysis of the crystal structure of, it is proposed that diastereoselective ortho-deprotonation directed by Ugi's amine may be ascribed to the different hindrance exerted by methyl group at chiral C.
