โฆ Synopsis
Recently, several groups have expressed interest in employing chiral catalysts in phasetransfer reactions in order to achieve absolute asymmetric syntheses.' The attractiveness of this "pseudo-enzymic" process is obvious. The purpose of this communication is to point out one' factor which does not seem to have been specifically recognized and which bears on the question of catalyst structure.

The ability of chiral anions, for example bis[1,1%-bi-2-naphtholato]borate, to induce asymmetry in the reactions of prochiral cations was investigated. Ion-pairing of a borate anion with an aziridinium ion was demonstrated by NMR spectroscopy. The addition of N-methyl indole to an iminium ion (benzy
