Facile stereoselective syntheses of goniodiol, 8-epi-goniodiol and 9-deoxygoniopypyrone
Prasad, Kavirayani R.,Gholap, Shivajirao L.
, p. 4679 - 4682 (2007)
Stereoselective syntheses of the bio-active styryllactones goniodiol and 9-deoxygoniopypyrone were accomplished from d-(-)-tartaric acid. The key step involves the elaboration of a γ-hydroxy butyramide to the styryllactones via high yielding stereoselecti
