A simple method for the preparation of optically active (+)- and (−)-1-ferrocenylethanol has been developed, which consists of a stereospecific cleavage of the carbon—sulphur bond in resolved (+)- and (−)-S-(1-ferrocenylethyl)-thioglycolic acids brought about by mercuric chloride in the presence of water.
The 1-ferrocenyl-2-methyl-1-propylamine (2a)is the most effective chiral template in asymmetricallyinduced peptide synthesis by stereoselectivefourcomponentcondensation (4CC). Two routes for the synthesis of this amine via its N,N-dimethyl derivative (12a) an described. One route involves the conversion of 12a into the corresponding azide 14a by treatment with methyl iodide/sodium azide in diglyme/water
