Surprise, surprise! An unexpected skeletal rearrangement was developed into a chemo‐ and stereoselective synthesis of α‐allyl and allenyl lactones with challenging substitution patterns (see scheme; EWG=electron‐withdrawing group). The generality, unique features, and synthetic potential of this reaction were probed and a mechanism was proposed.

The microwavespectrum of the normal species of the gauche, gauche isomer of ally1 alcohol has been reassigned and rotational and centrifugal distortion constants have been determined. Rotational constants of nine deuterated species, three carbon-13 species and the oxygen-18 species have also been obtained. These data were used to estimate structural parameters by least-squares fitting of the effective
