In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Safety of 2-(tert-Butoxycarbonyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 166591-85-1, name is 2-(tert-Butoxycarbonyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid. In an article£¬Which mentioned a new discovery about 166591-85-1
A high-optical-purity 1 – [tetrahydro-2-furyl] ethanone industrial preparation method (by machine translation)
The invention discloses a high-optical-purity 1 – [tetrahydro-2-furyl] ethanone industrial preparation method, belongs to the field of chemical synthesis, comprising the following steps: with tetrafuran formic acid as the raw material, reaction with carbonyl diimidazole, then adding malonic acid asian different propyl ester for condensation, then hydrolyzed in acidic conditions, the final extraction, concentrated to obtain product acetylprotoaescigenin tetrahydrofuran; the invention to prepare the high-optical-purity 1 – [tetrahydro-2-furyl] ethanone process, low cost of raw materials, do not need to use the Grignard reagent, stable product characteristics, the purity can be up to 98% or more, the optical purity can be up to 99% or more, the yield can reach 70% or more; the process after the actual commercial production verification, the quality is stable, mild reaction conditions, the operation is safe and reliable, process repeatability is good, the production cost is low, is a reliable high-optical-purity 1 – [tetrahydro-2-furyl] ethanone industrial preparation method.
