Then they combine the resulting enantiomeric mixture of ammonium bromide salts with the chiral compound 1,1’-bi-2-napthol (BINOL). Depending on which isomer of BINOL the team puts in ...

A characteristic of chiral compounds is that they occur as isomers with two (or more) identical but mirror-image structures that, as Gan's research indicates, while chemically identical ...

The group’s straightforward approach can be used to deracemize mixtures of many types of chiral aldehydes.

A unique example is the emissions of plants. These contain several chiral compounds that are naturally present in both chiral forms, the D- and L-isomers or enantiomers. A prominent example is the ...

The human body is so selective in its responses to chiral compounds that one isomer may produce a desired effect, while the other may be ineffective, and sometimes even toxic, so it is necessary ...

The technique relies on observation of the behavior of optical isomers. Molecules with the ... the NMR spectroscopy to decompose the signal of chiral activity of a compound. The research team ...

It is an important direction to develop efficient and convenient synthesis of chiral amines in organic synthetic chemistry. However, conventional catalytic synthesis methods, such as imine and ...

By incorporating electron-donating groups to the phenyl rings of imine linkages ... In this work, they further developed chiral organocatalytic functions based on these stable COFs.

The chiral capillary column coated with three-dimensional ... thanks to the presence of bulky iso-propyl groups that shield the dynamic imine linkages. Moreover, the precisely defined COF channels ...
