Popis: The chemistry and stereochemistry of flav-3-ene derivatives are discussed. Three of the four possible racemates of 4-acetoxy-3-bromoflavans are described; the fourth racemate was obtained in a mixture with another isomer. Syntheses of trans-3-hydroxyflavan, the parent compound of the catechin series and of the acetate of cis -3-hydroxyflavan, parent compound of the epicatechin series, are outlined.
