资源简介：
Metal-catalyzed,
double Claisen rearrangement of a bis-allyloxyflavone
has been utilized to enable a concise synthesis of the hydrobenzofuro[3,2-b]chromenone core structure of the natural products
sanggenon A and sanggenol F. In addition, catalytic, enantioselective
[4+2] cycloadditions of 2′-hydroxychalcones have
been accomplished using B(OPh)3/BINOL complexes. Asymmetric
syntheses of the flavonoid Diels–Alder natural products sanggenons
C and O have been achieved employing a stereodivergent reaction
of a racemic mixture (stereodivergent RRM) involving [4+2] cycloaddition.
