An N,N′-dicyclophane-substituted carbene analogous to 1a and a related Rh complex have been reported recently: Y. D. Ma, C. Song, C. Q. Ma, Z. J. Sun, Q. Chai, M. B. Andrus, Angew. Chem. Int. Ed. 2003, 42, 5871. Interesting results were obtained in the asymmetric addition of arylboron reagents to enones (ee up to 98%).

Aminoferrocene was first synthesized by Nesmeyanov (ref.[25]), who treated lithiated ferrocene with the O-benzyl ether of hydroxylamine and isolated the product in 25% yield. In the same year Arimoto and Haven synthesized aminoferrocene (ref.[26]) from ferrocenecarboxylic acid by using the Curtius synthetic strategy, but the overall yield was lower than 20%. Other approaches including Beckmann rearrangement from the oxime proved fruitless. Lehner and Schlögl, in 1970 (ref.[27]), reported the synthesis of planar-chiral (R)-1-amino-2-methylferrocene in 26% yield from (R)-2-methylferrocenecarboxylic acid by a modified procedure and determined its absolute configuration. The approach presented here differs from Schlögl's approach in various reaction conditions such as temperatures, solvents, the activation of the carboxylic acid and the fact that the sequence was performed in two steps in 82% yield. A recent example of a high yielding (80%) Curtius degradation sequence leading to achiral aminoferrocene can be found in ref.[28]

The amines 9a and 9b could have been produced directly from the isocyanate by adding water instead of benzylic alcohol but the purification and storage of the air-stable carbamate 8 proved to be more convenient.
