资源简介：
Alkyne oxazoles of general structure I are transformed directly to furo[2,3-b]phenol derivatives II by a sequence involving intramolecular Diels−Alder/retro-Diels−Alder reaction followed by tautomerization. Suitably functionalized phenols II undergo an intramolecular phenol−dienone−aldol condensation, generating the A,B,E-ring skeleton III characteristic of the viridin (1) class of furanosteroids.
