DOI: 10.1021/acs.orglett.1c03043
Abstract: A Brønsted acid-catalyzed 1,4-addition hydrothiolation of branched 1,3-dienes was explored for the first time. A solvent-controlled divergent synthesis of sulfides is also disclosed. Use of acetonitrile as a solvent gave allylic sulfides as hydrothiolation products,… read more here.

DOI: 10.1021/acs.orglett.2c02642
Abstract: Catalyst-controlled divergent reactions of 2,3-disubstituted indoles with propargylic alcohols were developed for the first time. In the presence of TsOH or B(C6F5)3 as catalyst, 2,3-disubstituted indoles reacted smoothly with 3-alkynyl-3-hydroxyisoindolinones to afford 3H-benzo[b]azepines by selective… read more here.

DOI: 10.1021/acs.orglett.3c00472
Abstract: Transition metal-controlled divergent annulation reactions of azomethine imines with iodonium ylides via C-centered [1,2]-rearrangement have been developed. The azomethine imino group, as a switchable and transient directing group (DG), underwent intramolecular nucleophilic addition and in… read more here.
