Sesquiterpene constituents of two liverworts of genus diplophyllum: Novel eudesmanolides and cytotoxicity studies for enantiomeric methylene lactones
TL;DR: In this paper, the enantiomers of diplophyllin were obtained on acid isomerization of isoalantolacetone (IoT) for human epidermoid carcinoma (KB cell culture, ED50⋍ 8 μ g ml ) than its enantiomer.

Furan-Based o-Quinodimethanes by Gold-Catalyzed Dehydrogenative Heterocyclization of 2-(1-Alkynyl)-2-alken-1-ones: A Modular Entry to 2,3-Furan-Fused Carbocycles
TL;DR: A strategy for in’situ generation of furan-based ortho-quinodimethanes by the gold(I)-mediated dehydrogenative heterocyclization of 2-(1-alkynyl)-2-alken-1-ones in the presence of pyridine N-oxide under mild reaction conditions was developed.
