By combining substituted anilines with functionalized orthoesters, an efficient and connective methodology for the preparation of benzoxazole, benzothiazole, and benzimidazole derivatives has been established. The versatility of this approach enables the development of new libraries of heterocycles containing multifunctional sites.

Isomerization issues have been encountered during the ring-closing metathesis (RCM) step of a new approach towardspentalenene. This paper describes the mechanisticinsights gained during the study of this side reaction from a substrate perspective. Isomerization issues have been encountered during the RCM step of a new approach towardspentalenene.
