Stereospecific synthesis and (chir)optical redox properties of helicenoid-based phosphepine as well chiral P-containing polycyclic aromatic hydrocarbons are presented.

Since their discovery, cyclodextrins have widely been used as green and easily available alternatives to promoters or catalysts of different chemical reactions in water. This review covers the research and application of cyclodextrins and their derivatives in asymmetric and stereospecific syntheses, with their division into three main groups: (1) cyclodextrins promoting asymmetric and stereospe...
