An organo-catalyzed photoelectrochemical alkene radical cation-triggered semipinacol rearrangement for the ring-contraction of arylidenecyclobutanols was developed, which enables access to diverse cyclopropanes under mild conditions.
This review provides a comprehensive summary of the origin, activities, and biosynthesis of spirooxindole-containing alkaloids derived from a variety of organisms, including actinomycetes, cyanobacteria, fungi, plants, and invertebrates.
Chiral BINAM-derived sulfide and boron trifluoride etherate cocatalyzed enantioselective electrophilic selenylation/semipinacol rearrangement of 1-(1-arylvinyl)cyclobutanols was developed for the first time.
This review provides a complete overview of the advances in the semipinacol rearrangement-mediated 1,2-group migration onto metal carbene centers which were reported in the past decades.
A chiral sulfide/B(C6F5)3/phosphoric acid co-catalyzed highly regio- and enantioselective tandem electrophilic sulfenylation/semipinacol rearrangement of allenols is developed for the first time.
