The enantioselective oxyarylation of (E)-6-aryl-1-silyloxylhex-3-ene was achieved using a lactate-based chiral hypervalent iodine(III) reagent in the presence of boron trifluoride diethyl etherate. The silyl ether promotes the oxidative cyclization, and enhances the enantioselectivity. In addition, the corresponding aminoarylation was achieved.
Does the Wittig-Still rearrangement proceed via a metal free carbanion?

The steric course of [2,3] rearrangements of allyloxy methanides is almost not affected by the counterion (M = Li, Na, K, Rb, Cs) as demonstrated by the nearly metal independent E,Z and anti,syn selectivities of rearrangements 4→6 and 7→8, respectively.
