A new and mild palladium(II)-catalyzed reaction for the intramolecular acyloxylation/cyclization of 2-(3'-alkenyl)indoles was developed. The newly formed cycles involve oxygen-containing functionalized groups, which might be transferred further to provide other indole derivatives.

The reaction of (2-(acetoxymethylene)-1,3-butadiene)Fe(CO)(3) (8) or ((acetoxymethylene)trimethylenemethane)Fe(CO)(3) (9) with weak carbon nucleophiles in the presence of BF3 . Et(2)O gives the corresponding substituted (trimethylenemethane)Fe(CO)(3) complexes as the major product. Applicable nucleophiles include trialkylaluminums, allyltrimethylsilane, and 2-((trimethylsilyl)oxy)-1-propene. This reaction proceeds in a stereospecific fashion; reaction of 12 gives a single (trimethylenemethane)iron product. The reaction of (1,2-bis(acetoxymethylene)-1,3-butadiene)Fe-(CO)(3) (20) with allyltrimethylsilane gives a (TMM)Fe(CO)(3) product in which two new C-C bonds have been formed in one reaction. Reaction of TMMFe(CO)(3) (1a) and substituted derivatives with carbanions, followed by workup with trifluoroacetic acid, gives the corresponding methallylated product. Applicable nucleophiles include anions derived from diphenylmethane, ethyl isobutyrate, isobutylnitrile, and 2-phenyl-1,3-dithiane. Use of allyl bromide in place of trifluoroacetic acid gives 6-substituted 5-methylene-1-hexenes as products, the result of a three-component coupling.
