Abstract

A mixture of solids As and Bs in equilibrium with the dissolved compounds A1 and B1 is transformed completely into one pure solid, say Bs, if the dissolved compounds A1⇌ B1 are equilibrating in solution. This is applied to transform 1∶ 1 mixtures of solid diastereomeric amygdalates (2-hydroxy-2-phenylacetates; mandelates)(R, R)-3+(S, R)-3 prepared from racemic α-amino nitriles (R, S)-1 with (R)-mandelic acid 2 into stereochemically pure ...
