Chemistry is traditionally divided into organic and inorganic chemistry. Recommanded Product: 143900-44-1. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 143900-44-1
The invention relates to preparation of chirality-1-t-butyloxycarboryl-3-hydroxy piperidine and a method for chirality turning. The preparation mainly comprises the following steps: resolving N-benzyl-3-hydroxy piperidine as a raw material to obtain a (S) or (R)-1-benzyl-3-hydroxy piperidine camphorsulfonic acid salt, performing alkali freedom to obtain (S) or (R)-1-benzyl-3-hydroxy piperidine, performing palladium carbon hydrogenation debenzylation/t-butyloxycarboryl protection to obtain (S) or (R)-1-t-butyloxycarboryl-3-hydroxy piperidine, acylating substituting sulfonyl chloride of (R) or (S)-1-substituting-3-hydroxy piperidine as a raw material to obtain (R) or (S)-1-substituting-3-hydroxy piperidine sulfonate, substituting by using substituting carboxylate to obtain (S) or (R)-1-substituting-3-hydroxy piperidine carboxylic ester, and performing alkaline hydrolysis to obtain (S) or (R)-1-substituting-3-hydroxy piperidine. The synthesis route is gentle in reaction condition, and is applicable to industrial large-scale production.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 143900-44-1, you can also check out more blogs about143900-44-1
