Nitrile addition to cyclohexadienyium-Fe(CO)3 perchlorate salt provides an efficient entry into the angularlysubstituted cis-fused perhydroisoquinoline ring system. The key steps in the assembly of the angularlysubstituted cis-octahydroisoquinoline ring are the transformation of the nitrile to an N-(benzylmethylencie)amino group and a diastereoselective intramolecular Michael reaction to form the

Nitrile adducts have been obtained in high yield from tricarbonyliron(1+) salts by the use of the reagents trimethylsilyl cyanide and tetra-n-butylammonium cyanide. Trimethylsilyl cyanide is a versatile reagent which is superior to sodium cyanide for this purpose, and its use is the method of choice in cases where a terminal alkyl group is present on the dienyl system. Tetra-n-butylammonium cyanide
