Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 3393-45-1, is researched, Molecular C5H6O2, about Catalytic asymmetric synthesis of chiral phenols in ethanol with recyclable rhodium catalyst, the main research direction is chiral phenol enantioselective preparation green chem; alkene bearing EWG hydroxylated phenylboronic acid arylation rhodium catalyst.Name: 5,6-Dihydro-2H-pyran-2-one.
A general method to access diverse chiral phenols by rhodium-catalyzed asym. conjugate arylation using hydroxylated arylboronic acids in ethanol was developed. Recycling of the rhodium catalyst by flash chromatog. on silica gel was feasible in this system. The synthetic utility of the strategy was demonstrated by efficient synthesis of chiral drug tolterodine.
