Unsymmetrical silyl bis-enol ethers have been developed as effective substrates for synthesizing quaternary centers from tetralone derivatives through oxidative carbon-carbonbondformation. The derived products are shown to be highly versatile intermediates that may be used to generate diverse structures such as cyclopentenones, 2H-pyrroles, and spirocyclic pyrrolidines.

Palladiumcatalysed processes involving sequential carbonylation-cyclisation-carbometallation-anion capture from Sn(IV) and B(III) are described. These molecular queuing processes occur in good yield under 1 atm. of carbon monoxide. Reactivity/selectivity guidelines are delineated for carbopalladation, acylpalladation and anion capture.
