  • Chirality in 'real-time'

    In nature, certain molecules with the same chemical composition, can exist in two different shapes that are mirrors images of each other, much like our hands. This property is known as "chirality" and molecules with different chirality are called enantiomers. Enantiomers can exhibit entirely differe more

  • Photochemical deracemization of chiral compounds achieved

    Enantiomeric molecules resemble each other like right and left hands. Both variants normally arise in chemical reactions. But frequently only one of the two forms is effectual in biology and medicine. Hitherto, completely converting this mixture into the desired enantiomer was deemed impossible. Dep more

  • A new path through the looking-glass

    Exploring the mystery of the molecular handedness in nature, scientists have proposed a new experimental scheme to create custom-made mirror molecules for analysis. The technique can make ordinary molecules spin so fast that they lose their normal symmetry and shape and instead form mirrored version more

A Brief Guide to Types of Isomerism in Organic Chemistry

In organic chemistry, isomers are molecules with the same molecular formula (i.e. the same number of atoms of each element), but different structural or spatial arrangements of the atoms within the molecule. The reason there are such a colossal number of organic compounds – more than 10 million – is more

  • Water instead of mineral oil

    Optical active substances made from chiral catalysis form the basis of many drugs. Expensive precious-metal catalysts are required for the chemical production, which due to their thermal instability decompose at high temperatures and can therefore only be used once. The innovative process of DexLeChem GmbH makes it possible for the first time to use these precious-metal catalysts made from rhodium, ruthenium or iridium more than once, without modifying them. At the same time, reaction occurs in aqueous solutions instead of mineral-oil-based solvents, which increases the sustainability of the process. This is a milestone in catalysis and a real opportunity for the pharmaceutical industry. more

  • Molecules in the mirror

    In 1871 the children‘s book “Through the Looking-Glass – And What Alice Found There” by the English author Lewis Carroll, in which Alice enters a world behind the mirror, was published. She explains to her cat: “First there’s the room you can see through the glass – that’s just the same as our drawing room, only the things go the other way. …How would you like to live in Looking-glass House, Kitty? I wonder if they’d give you milk in there? more

Axial chirality

Axial chirality Axial chirality is a special case of chirality in which a molecule does not possess a stereogenic center (the most common form of chirality in organic compounds ) but an axis of chirality - an axis about which a set of substitu ... more
