Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. name: (R)-Tetrahydrofuran-3-yl 4-methylbenzenesulfonate. Introducing a new discovery about 219823-47-9, Name is (R)-Tetrahydrofuran-3-yl 4-methylbenzenesulfonate
A method for preparing graciousness Geleg only (by machine translation)
The invention discloses a method for preparing graciousness Geleg only, comprises the following steps: 1) the compound 5 after through Grignard exchange reaction with the glucose lactone derivative 6 reaction to obtain compound 7; Wherein X is bromine or iodine, LG is chlorine, bromine, armor sulphur acyloxy or paratoluene sulfonyloxy, PG is acetyl, bi acyl or benzoyl; 2) under the action of alkali compound 7 of deprotection of the final product is obtained positions near to the graciousness Geleg 8 compound; The preparation routes the operation is simple, shortening reaction step, not only higher yield, purity of the obtained products is also high, and suitable for production. (by machine translation)
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.name: (R)-Tetrahydrofuran-3-yl 4-methylbenzenesulfonate, you can also check out more blogs about219823-47-9
