ortho-Mercaptobenzoic acid and ortho-mercaptophenols were discovered as efficient thiol catalysts of both the intramolecular Morita–Baylis–Hillman (MBH) and Rauhut–Currier (RC) reaction. High reaction rates were achieved under mildly basic, aqueous conditions. The unprecedented catalytic activity of these protic nucleophiles could originate from a Brønsted acid induced destabilization of intermediate

acid‐mediated cascade reaction induced by conjugate addition of sulfinamides to dienediones has been developed. This highly efficient Rauhut–Currierreaction enables the rapid, high‐yielding construction of sulfonatedcyclopentanes with three contiguous stereogenic centers in a single operation starting from simple sulfinamides. This process constitutes the first example of sulfinamide‐promoted cycloisomerization

The noncovalent S•••O bonding interaction is an evolutionary force that has been smartly exploited by Nature to modulate the conformational preferences of proteins. The employment of this type of weak noncovalent force to drive chemical reactions is promising yet remains largely elusive. Herein, we describe a dual chalcogen-chalcogen bonding catalysis strategy that the distinct chalcogen atoms simultaneously
