    Synthesis of Both Enantiomers of Flavanone and 2-Methylchromanone
    摘要:
    An efficient enantiospecific synthesis of the (R)- and (S)-enantiomers of flavanone and 2-methylchromanone is described. The key steps are a C,C-bond formation by ring opening of a chiral epoxide with a dithiane anion, followed by a Mitsunobu cyclization. The products obtained have high enantiomeric purity.
