Iridium-Catalyzed Stereoselective Allylic Alkylation Reactions with Crotyl Chloride
Hethcox, J. Caleb,Shockley, Samantha E.,Stoltz, Brian M.
, p. 16092 - 16095 (2016)
The development of the first enantio-, diastereo-, and regioselective iridium-catalyzed allylic alkylation reaction of prochiral enolates to form an all-carbon quaternary stereogenic center with an aliphatic-substituted allylic electrophile is disclosed. The reaction proceeds with good to excellent selectivity with a range of substituted tetralone-derived nucleophiles furnishing products bearing a newly formed vicinal tertiary and all-carbon quaternary stereodyad. The utility of this protocol is further demonstrated via a number of synthetically diverse product transformations.
Gold-catalyzed ring-expansion through acyl migration to afford furan-fused polycyclic compounds

A gold-catalyzed ring-expansion reaction of alkynones to access furan-fused polycyclic compounds is reported. Mechanistic studies revealed that the reaction might occur through a tandem 1,2-acyl migration/Friedel-Crafts reaction.
Photolysis of cyclic enol esters in the presence or absence of a single electron transfer photosensitizer
Climent,Garcia,Iborra,Miranda,Primo
, p. 9289 - 9296 (2007/10/02)
The photochemistry of enol esters 1 is dominated by electrocyclic ring opening (1b → 3+4), 1,3-acyl migration (1c,d → 6c,d) and [2 + 2] dimerization (1d → 11). Photosensitization with triphenylpyrylium tetrafluoroborate (TPT) enhances formation of oxidation products (1b → 5,1c,d → 9c,d + 10c,d), presumably through the intermediacy of radical cations 1b-d+.
