[reaction: see text] A short and convenient diastereoselective synthesis of all-carbon spirocylic molecules was developed. A straightforward protocol that involves rearrangement of the diene-Fe(CO)(3) complex followed by cyclization delivers the desired product. The reaction substrates were easily prepared by reaction of an appropriate nucleophile and a cyclohexadienyl-Fe(CO)(3) cation.

Stereochemical requirements of oxidative cyclizations in extended iterative organoiron-mediated routes to alkaloids.
TLDR
The cis relative stereochemistry of the oxidative cyclization product, the exo delivery of hydride to the 1-arylcyclohexadienyliron(1+) complex, and the 2-aryl-5-endo-methoxy relative stereochemical of the rearranged product were proved by X-ray crystallography. Expand
Selective synthesis and reactivity of eta5-arylcyclohexadienyliron complexes.
TLDR
A series of aryl-substituted cyclohexadienyliron complexes have been prepared by a general procedure that determines regioselectivity by correctly positioning leaving groups in the precursor complexes, which reverts reactivity to the ipso pathway with stabilised enolate nucleophiles. Expand

TLDR
A new, general method is described by the intramolecular ipso-halocyclization of 4-(p-unsubstituted-aryl)-1-alkynes for the synthesis of spiro[4,5]trienones, which can be applied in constructing the azaquaternary tricyclic skeleton via Pd-catalyzed Heck reaction. Expand
