Synthetic applications of oxonium ylide rearrangements will be presented in two sections, the first concerning [2,3]-sigmatropic rearrangements and the second covering [l,2]-shifts. To begin, a number examples which assemble furan-3-one and pyran-3-one rings via [2,3]-... [Pg.609]

It has been reported that the conformational isomer distribution of diazoacetoacetate and the metal carbene intermediate is reflected in Rh(II)-catalysed oxonium ylide forming reactions of 3-(fra 5 -2-arylvinyl)tetrahydropyranone-5-diazoacetoacetates that give diastereoisomeric products for the symmetry-allowed [2,3]- and the formally symmetry-forbidden [l,2]-oxonium ylide rearrangements (Scheme 153). ... [Pg.521]
