A study on the synthesis of antiangiogenic (+)-coronarin A and congeners from (+)-sclareolide

Coronarin A 1, epi-coronarin A 2 and some synthetic intermediates 14a and 14b synthesized from sclareolide exhibit good growth inhibition activities on HUVEC proliferation. In particular, coronarin A 1 and epi-coronarin A 2 effectively suppressed the growth factor induced tube formation of HUVEC at the concentration of 10 μg/mL.
