Fischer projection diastereomers

Two older prefixes still commonly used to distinguish diastereomers are threo and erythro. In the case of saccharides, when drawn in the Fischer projection the erythro isomer has two identical substituents on the same side and the threo isomer has them on opposite sides. When drawn as a zig-zag chain, the erythro isomer has two identical substituents on different sides of the plane (anti). The names are derived from the diastereomeric four-carbon aldoses erythrose (a syrup) and WebFischer projections are just another way of drawing compounds contacting chirality centers. They are used for drawing molecules containing multiple chirality centers with the main idea of not having to draw the wedge and …

WebA Fischer projection is a drawing of a 3D molecule as a flat structure. The chiral carbons are represented by crossed lines. In addition to carbohydrates, it is useful for other molecules that have two or more chiral carbons. Fischer projections are useful for differentiating between enantiomers, diastereomers, and meso compounds. WebWe know stereoisomers that are not mirror images are called Diastereomers. They are either geometrical isomers or compounds containing two or more chiral centres. A Diastereomer is called erythro if its Fischer projection shows similar groups on the same side of the molecule.
