Electrophilic Selenium, Selenocyclizations

TLDR: The most important progress made in the last ten years in the production of new electrophilic selenium reagents as well as in their reactivity towards unsaturated compounds are presented and discussed as discussed by the authors.

Abstract: The most important progress made in the last ten years in the production of new electrophilic selenium reagents as well as in their reactivity towards unsaturated compounds are presented and discussed Several new selenium-promoted, ring-closure reactions are illustrated and the factors controlling the selectivity of the cyclization process are discussed One-pot selenenylation-deselenenylation sequences, which occur using only catalytic amounts of the organoselenium reagents, are presented Finally, the efficient asymmetric syntheses, which are carried out with the recently described chiral non-racemic electrophilic selenenylating agents, are also surveyed
