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 ...

Many drugs on the market today contain at least one molecule that is chiral. Often only one of the configurations, or isomers, is effective in the body. In some cases, the other isomer may even be ...

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 ...

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

Chiral PCBs are particularly dangerous because they have more chlorine atoms, which are hard for the body to break down, so they can accumulate in the body easily. Also, their isomers are ...

In summary, a novel chiral element—staircase chirality was discovered. Individual staircase isomers were selectively synthesized by simultaneously using two chiral auxiliaries: an amide and a ...

In the Chemical Science paper, the team demonstrated this using acid-stable chiral imine cages to catalyse the supramolecular polymerisation of TPPS (tetrakis(4-sulfonatophenyl)-porphyrin)) as a ...

Your hands are an example of a chiral object. When chirality is applied to molecules, the two mirror-image forms of the molecule are referred to as isomers, and are often called the 'left-handed' and ...
