A base-catalyzed protocol is reported for the construction of 1,3-thiazolidine-2-thione scaffolds bearing quaternary carbon centers from disulfide and α-tertiary propargylamines. The reaction proceeds using low catalyst loading, under ambient temperatures, in absence solvent. Various propargylamines have been employed, affording a series previously unreported thiazolidine-2-thione compounds avoiding purification via column chromatography certain cases. We also describe one-pot strategy synthesis same products through KA2 coupling–CS2 incorporation approach. mechanism substituent-dependent catalytic behavior were studied combination detailed experimental computational studies.

Abstract An unprecedented post-Ugi Brønsted acid catalyzed fragmentation followed by in situ trapping of the alkylideneindolenine intermediate indole nucleophiles was developed to furnish novel bis(indolyl)acetamides. The amide fragment formed during this acid-catalyzed Ugi adduct also isolated and characterized. carboxylic amine components reaction were carefully chosen permit a simple water wash for removal obtain desired bis(indolyl)acetamides pure form.

The iron-catalyzed Suzuki–Miyaura cross-coupling of secondary propargyl electrophiles with lithium organoborates has been established. A propyl-bridged bulky bisphosphine ligand, SciPROP-TB, cooperated the TIPS substituent at alkyne terminal position to achieve reaction exclusive propargylic selectivity. features high functional group compatibility, regioselectivity, and yield a broad substrate scope. an optically active chiral bromide proceeds complete racemization, supporting mechanism involving radical formation.
