2-Chloro-1,3-dimethylimidazolinium chloride (DMC) (1) can act as a powerful dehydrating equivalent to DCC (2) under nearly neutral conditions. Its application to the construction of heterocycles through dehydration reactions is described.

New optically active β-amino alcohols, derived from various acyclic and cyclic amino acids with alkyl groups on the carbinol carbon atom, were used in the enantioselectivereduction of prochiralketones. The attachment of alkyl groups to the nitrogen atom of the catalyst (R)-1b was shown to influence favorably the enantioselectivity of the addition of diethylzinc to benzaldehyde. In both cases the
