Reference of 144542-43-8, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.144542-43-8, Name is (R)-Methyl 2-oxooxazolidine-4-carboxylate, molecular formula is C5H7NO4. In a Article，once mentioned of 144542-43-8
The first total synthesis of (+)-8-epi-xanthatin (1) has been achieved in 14 steps starting from the commercially available ester 24, which was converted into aldehyde 23 in six steps. An enantioselective aldol reaction of 23 gave 30, which was transformed into triflate 22 in four steps, setting the stage for a palladium-catalyzed carbonylation reaction to form acrylate 34. Compound 34 was then subjected to a deprotection/lactonization sequence to furnish enyne 21, which underwent a domino enyne ring-closing metathesis/cross metathesis process to form a seven-membered carbocycle and (E)-conjugated dienone, thereby completing the synthesis of 1. This domino ruthenium-catalyzed metathesis reaction thus serves as an efficient method to construct the core of xanthanolide and other sesquiterpene lactones.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 144542-43-8
