How many chiral centers does epinephrine have
WebApr 15, 2024 · Ephedrine has two chiral centres and can therefore exist in the form of four stereoisomers: 1R,2S- (-)-ephedrine, 1S,2R- (+)-ephedrine, 1S,2S- (+)-pseudoephedrine and 1R,2R - (-)-pseudoephedrine ( Table 1 ). WebDec 17, 2024 · Typically, you can only have diastereomers when the molecule has two or more chiral centers. The maximum number of possible stereoisomers that a molecule can have is a function of 2 n, where n is the number of chiral centers in the molecule. Therefore, a molecule with five chiral centers can have up to 2 5 or 32 possible stereoisomers! As …
