Synthesis of enantioenriched Betti base precursors containing a congested quaternary stereocenter was described. In a chiral phosphoric acid-catalyzed reaction, a series of in-situ generated isoindolinone-derived ketimines and phenol derivatives yield products in good to excellent yields and moderate enantioselectivities. Conversion of the obtained products into chiral Betti bases with the retention of the optical purity was demonstrated. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Reference of 103-16-2).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Reference of 103-16-2
