Reference of 24621-61-2, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 24621-61-2, Name is (S)-Butane-1,3-diol,introducing its new discovery.
Stereoselective Aldol-Type Cyclization Reaction Mediated by Dibutylboron Triflate/Diisopropylethylamine
(Equation presented) Dibutylboron triflate/diisopropylethylamine mediated aldol-type cyclization provides an expedient route for the stereoselective synthesis of cyclic ethers in a single step. The method is highly efficient for the stereoselective synthesis of 4-cis-tetrahydropyranones. The reaction is proposed to proceed via an SN1-type mechanism through a chair-like transition state, in which both substituents occupy equatorial positions.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Reference of 24621-61-2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 24621-61-2, in my other articles.
