Presented herein is the Brønsted acid (MsOH) mediated electrophilic sulfenylacyloxylation of o-alkynylbenzoates via alkyne activation by in-situ formed sulfonium cations from bench-stable N-thioaryl/alkyl-succinimides followed by the intramolecular regioselective cyclization. The transformation provides access to structurally diverse 4-sulfenylisocoumarins in 77–98% yields with broad functional group
The present invention relates to cyclobenzaprine analogs and amitriptyline analogs, including deuterated forms useful for treatment or prevention of symptoms associated with post-traumatic stress disorder.

Convenient silylborane precursors for introducing N,B-bidentate boryl ligands onto transition metals were designed, prepared, and employed in ready formation of irdium(III) complexes via Si-B oxidative addition. A practical, efficient catalytic ortho-borylation reaction of arenes with a broad range of directing groups was developed using an in situ generated catalyst from the silylborane preligand 3c and [IrCl(COD)](2).
