WebA new typo of optically active inclusion host derived from natural camphor is described, enabling useful enantiomer separation of chiral compounds cocrystallization; the structural rationale of an inclusion complex with ()-(+)-phenyloxirane based on X-ray determination and a molecular modelling study is reported. WebA chiral compound can contain no improper axis of rotation (S n), which includes planes of symmetry and inversion center. Chiral molecules are always dissymmetric (lacking S n) but not always asymmetric (lacking all symmetry elements except the trivial identity). Asymmetric molecules are always chiral. ... which is chiral and optically active ( ...
