Abstract
In this report, we have described a FeCl3-catalyzed process involving intramolecular annulation of o-phenoxy diarylacetylenes via hydroarylation to afford a series of biologically potent fused seven-membered (6-7-6) ring compounds under mild reaction conditions. This reaction was believed to proceed through Friedel-Crafts type sequential carbometallation followed by protonation to produce phenyldibenz[b,f]oxepines. This method was also extended to synthesize seven-membered rings that are fused with coumarins.

Abstract
The reactivity of 2-(2-alkynylphenoxy)anilines under PdI2 /KI-catalyzed oxidative carbonylation conditions has been studied. Although a different reaction pathway could have been operating, N-palladation followed by CO insertion was the favored pathway with all substrates tested, including those containing an internal or terminal triple bond. This led to the formation of a carbamoylpalladium species, the fate of which, as predicted by theoretical calculations, strongly depended on the nature of the substituent on the triple bond. In particular, 8-endo-dig cyclization preferentially occurred when the triple bond was terminal, leading to the formation of carbonylated ζ-lactam derivatives, the structures of which have been confirmed by XRD analysis. These novel medium-sized heterocyclic compounds showed antitumor activity against both estrogen receptor-positive (MCF-7) and triple negative (MDA-MB-231) breast cancer cell lines. In particular, ζ-lactam 3 j' may represent a novel and promising antitumor agent because biological tests clearly demonstrate that this compound significantly reduces cell viability and motility in both MCF-7 and MDA-MB-231 breast cancer cell lines, without affecting normal breast epithelial cell viability.

Abstract
Zerumbone 1 is an 11-membered cyclic sesquiterpene obtained from the rhizomes of Zingiber zerumbet SMITH (Zingiberaceae). In this study, we investigated the structure-activity relationship of 1, α-humulene (2), tetrahydrozerumbone stereoisomers (3-5), and tetrahydrozerumbone derivatives (6-9). The oxygen-containing functional groups and the configurations at C1 and C2 contributed to the spontaneous locomotor activity reduction of zerumbone 1 and derivatives 2-9.
