Iodobenzene-catalyzed alpha-acetoxylation of ketones. in situ generation of hypervalent (diacyloxyiodo)benzenes using m-chloroperbenzoic acid.
TL;DR: It is found that when the reaction was carried out in the absence of a catalytic amount of iodobenzene, Baeyer-Villiger oxidation of a ketone took place, and it is noted that use of water and BF3.Et2O is crucial to the success of this alpha-acetoxylation.

X-Ray crystal structure of rocaglamide, a novel antileulemic 1H-cyclopenta[b]benzofuran from Aglaia elliptifolia
TL;DR: The structures and relative stereochemistries of recaglamide, a novel antileukemic 1H-cyclopenta[b]benzofuran isolated from Aglaia elliptifolia, and dehydrorocaglamides, derived from rocaglide, have been established from spectral and single-crystal X-ray analysis as discussed by the authors.
