The chirality center of the following molecules is to be identified. Concept introduction: Threose is a four-carbon monosaccharide with molecular formula C 4 H 8 O 4 . Enflurane (2-chloro-1, 1, 2,-trifluoroethyl-difluoromethyl ether) is a halogenated ether. Developed by Ross Terrell in 1963, it was first used clinically in 1966.

Question

Chloramlhenicol, a powerful antibiotic in 1947 from the streptomyces venezuelae bacterium, is active against a broad spectrum of bacterial infections and is particularly valuable against typhoid fever. Assign R or S configurations to the chirality centers in chloramphenicol

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
