Can organocatalysts that incorporate fluxional groups provide enhanced selectivity in asymmetric transformations? To address this issue, we have designed chiral 4-dimethylaminopyridine (DMAP) catalysts with fluxional chirality. These catalysts were found

Newly-designed optically active (salen)manganese(III) complexes (5) catalyze highly enantioselective benzylic hydroxylation and moderate level of enantiomer-differentiating oxidation (kinetic resolution) of the resulting benzylic alcohols. Thus, the enantiomeric excess of hydroxylation product was increased through kinetic resolution, as the reaction time was prolonged. For example, enantiomeric excess of 3,3-dimethylindan-1-ol, the hydroxylation product of 1,1-dimethylindan using 5a as a catalyst in chlorobenzene, was 84% alter 10 min and 90% after 20 h.

The photostimulated reactions of p-iodoanisole (2) and 1-iodonaphthalene (7) with 2-naphthoxide ions in liquid ammonia gave the corresponding 1-aryl-2-naphthols as the only substitution product.These reactions are proposed to proceed via the SRN1 mechanism for nucleophilic aromatic substitution.
