Chiral selection rule
WebAug 19, 2024 · The chiral selection may take the form of conglomerate crystal formation or of selective homochiral aggregation in racemic crystals. When cocrystallization involves alkaline earth metal cations, such as Ca 2+ and Mg 2+ , which favour octahedral coordination, heterochiral complexation is observed in most cases, with formation of … WebThe rule of thumb is: chiral carbon centers are carbon atoms that are attached to four different substituents, that are placed at the corners of a tetrahedron. Chiral carbon atoms are also referred to as ‘stereogenic carbons’ or ‘asymmetrical carbon atoms’. Compound 1 has a chiral carbon center, because it is attached to four different ...
