Abstract
A tandem annulation reaction of allyl ketones and β-aryl ethenesulfonyl fluorides has been described. Under the catalysis of Brønsted base, allyl ketones reacted with β-aryl ethenesulfonyl fluorides through a tandem intermolecular Michael addition-intramolecular SuFEx process to afford γ-alkenylated δ-sultones in good to excellent yields. In this reaction, no additional base was needed, and 4 Å molecular sieves were used as efficient HF scavenger to restrict the neutralization and deactivation of the Brønsted base catalyst.
期刊介绍：
Organic chemistry is the fundamental science that stands at the heart of chemistry, biology, and materials science. Research in these areas is vigorous and truly international, with three major regions making almost equal contributions: America, Europe and Asia. Asia now has its own top international organic chemistry journal—the Asian Journal of Organic Chemistry (AsianJOC)
The AsianJOC is designed to be a top-ranked international research journal and publishes primary research as well as critical secondary information from authors across the world. The journal covers organic chemistry in its entirety. Authors and readers come from academia, the chemical industry, and government laboratories.
