In chemistry, stereoselectivity[1] is the property of a chemical reaction in which a single reactant forms an unequal mixture of stereoisomers during a non- stereospecific creation of a new stereocenter or during a non-stereospecific transformation of a pre-existing one. [2] .

2022年2月28日 · If more than one reaction could occur between a set of reactants under the same conditions giving products that are stereoisomers and if one product forms in greater amounts than the others, the overall reaction is said to be stereoselective.

2010年7月2日 · A stereoselective reaction is one that forms one stereoisomer selectively over another. Some stereoselective reactions are stereospecific, meaning that the stereochemistry of the product is determined by the stereochemistry of the starting material.

Something very important to keep in mind: stereospecific is the reaction can is physically limited to making a certain product(s) based on the stereochemistry of the starting materials, while stereoselective is the description of the reaction outcome …

• A stereoselective reaction is one in which a single reactant can give two or more stereoisomeric products, and one or more of these products is preferred over the others – even if the preference is very small. Stereospecific • In a stereospecific reaction, one stereoisomer of the reactant gives one stereoisomer of the product,

The fundamental difference between stereospecific and stereoselective reactions lies in the precision and exclusivity of stereoisomer formation. Stereospecific reactions yield a single stereoisomer as the sole product, while stereoselective reactions favor one stereoisomer over others but can still produce a mixture of stereoisomers.

2018年1月28日 · Stereospecific and stereoselective reactions are two types of reaction that can be found in organic chemistry. The main difference between stereospecific and stereoselective reactions is that a stereospecific reaction gives one specific product whereas stereoselective reaction gives multiple products. Reference: 1. “Stereospecificity.”

2023年5月6日 · A stereoselective reaction is the chemical reaction where one isomer of product forms preferentially over other isomer. The main reason of stereoselectivity is difference in steric and electronic effects in mechanistic pathways to produce final product. Stereoselective reactions are helpful for targeted synthesis of organic compounds.

When a given set of reactants undergoes multiple reactions in a given condition, then the products formed are called stereoisomers. One of these formed products is in a larger quantity than the others, and the entire reaction is called stereoselective reaction.
