A new thiourea catalyst is reported for the enantioselective cationic polycyclization of hydroxylactams. Both the yield and enantioselectivity of this transformation were found to vary strongly with the identity of a single aromatic residue on a common ca
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.
