Lamellar conglomerates

The 100-year history of this unusual crystalline form of organic racemates resulted so far in only nineteen (19!) examples, among which amino acids, helicenes, and one steroid are presented. It is expected that such lamellar conglomerates (LC) are much more numerous. The review provides a comparison of the properties of LC and plain conglomerates as a basis for the search of new LC, and describes the prospects of the practical LC application in enantioselective synthesis.
