Three selective variants of the Wittig reaction for the syntheses of 2-vinylindoles are described. The reactions are relatively easy to perform, exhibit E-selectivity, and are characterized by a good flexibility with regard to the functional groups present in the vinyl moiety.

sequential triple‐relay‐catalysis, provides an easy access to several structurally unique carbazoles including 2‐ and 3‐alkenylcarbazoles. This protectinggroup‐free method enabled one‐pot synthesis of alkaloids such as hyellazole and 6‐chlorohyellazole, and the formal syntheses of seven other alkaloids. Construction of the core structure, present in murastifoline A, murrafoline E, and related alkaloids was
The present invention is directed to novel multicyclic molecules that mediate enzymatic activity. In particular, the compounds may be effective in the treatment of diseases or disease states related to the activity of PARP, VEGFR2, and MLK3 enzymes, including, for example, neurodegenerative diseases, inflammation, ischemia, and cancer.

Readily available N-carbamoyl indolines can be converted into highly valuable 2-alkenyl and 2-alkyl indoles in a one-pot reaction, through an autotandem catalytic cascade promoted by an iridium complex. The process entails a dehydrogenationreaction initiated by an iridium-promoted C(sp3)–H activation, the addition of the resulting indole to an alkyne -or alkene-partner, and a spontaneous loss of the carbamoyl
