The first molybdenum-catalyzed allylic sulfonylation of tertiary allylic electrophiles is described. The method employs a readily accessible catalyst (Mo(CO)6/2,2′-bipyridine, both are commercially available) and represents the first example of the use of a group 6 transition metal-catalyst for allylic sulfonylation of substituted tertiary allylic electrophiles to form carbon-sulfur bonds. This atom economic and operationally simple methodology is characterized by its relatively mild conditions, wide substrate scope, and excellent regioselectivity profile, thus unlocking a new platform to forge sulfone moieties, even in the context of late-stage functionalization and providing ample opportunities for further derivatization through traditional Suzuki cross-coupling reactions.

A short formal synthesis of (±)-sporochnol A (1) is described. In this synthesis, the quaternary carbon center is formed by successive alkylations of the carbanion a to the nitrile in an arylacetonitrile derivative, followed by conversion of the nitrile g

Sporochnols, fish deterrents from a marine alga, were synthesized, using intramolecular C-H insertion of alkylidenecarbene as a key step to construct the chiral quaternary center.
