A PhI(OAc)2-promoted dioxygenation of allyl oximes, including one alkoxylation, has been developed. This reaction can give isoxazoline products bearing two contiguous tetrasubstituted carbons. Various oximes substrates bearing different aryl groups and tetrasubstituted-olefin moieties were compatible with the mild reaction conditions. A two-electron oxidation pathway was proposed based on results of preliminary mechanistic studies.
Reactions of substituted (2-butene-1,4-diyl)magnesium complexes with carboxylic esters and lactones: Formation of a versatile intermediate capable of generating substituted cyclopentenols, fused-ring cyclopentenols, or β,γ-unsaturated ketones

Reaction of the magnesium complexes of substituted 1,3-dienes with either carboxylic esters or lactones at low temperature (-78 to -10°C) generates the magnesium salt of a cyclopropanol. This intermediate can either be trapped as an acetate of the cyclopr
