WebAldol condensation occurs in aldehydes having α-hydrogen with a dilute base to give β-hydroxy aldehydes called aldols. This reaction is most commonly known as aldol … WebIntroduction. In 2007, our group reported the first enantioselective synthesis of (R)-2-isopropenyl-2,3-dihydrobenzofuran-4-ol 1 in 10 steps from resorcinol in an overall yield of 15.7%. 1 This was of importance as the 2-isopropenyl-2,3-dihydrobenzofuran moiety, possessing an asymmetric carbon at the 2-position, is found in a number of natural … north carolina school of art
