Weak force in action: In the title reaction, the palladium catalyst (see figure, left) uses weak CH×××O hydrogen bonding to control the absolute configuration of the new stereocenter. A similar palladium catalyst (right) used conventional NH×××O hydrogen bonding to guide stereoselection. Copyright

Pyrolysis of the title compound 3 at 400°C gave α-(2-hydroxyphenyl)-γ-butyrolactone (4) whose structure was confirmed by an alternative synthesis. A reaction mechanism via a phenyl ketene acetal is proposed.
