A variety of cyclic sulfonamides and sulfinamides could be selectively synthesized under Pd catalysis using haloarenes bearing amino groups and a sulfur dioxide (SO₂) surrogate. The amount of base was key in determining the selectivity. Mechanistic studies revealed that sulfinamides were initially formed via an unprecedented formal insertion of sulfur monoxide and were oxidized to sulfonamides in the presence of an iodide ion and DMSO.

Fan, Yi Chiao published the artcilePhosphine/Palladium-Catalyzed Syntheses of Alkylidene Phthalans, 3-Deoxyisoochracinic Acid, Isoochracinic Acid, and Isoochracinol, SDS of cas: 500563-90-6, the publication is Organic Letters (2012), 14(13), 3264-3267, database is CAplus and MEDLINE.

In this study, we used sequential catalysis-PPh₃-catalyzed nucleophilic addition followed by Pd(0)-catalyzed Heck cyclization-to construct complex functionalized alkylidene phthalans, e.g., I (R¹ = H, R, R² = H, OCH₂Ph, OMe, CF₃, etc., R³ = H, OCH₂Ph, OMe, Me, R⁴ = H, Me, MeO), rapidly, in high yields, and with good stereoselectivities (E/Z ratios of up to 1:22). The scope of this Michael-Heck reaction includes substrates bearing various substituents around the alkylidene phthalan backbone. Applying this efficient sequential catalysis, we accomplished concise total syntheses of 3-deoxyisoochacinic acid II (X = none, Y = CO₂H) isoochracinic acid II (X = O, Y = CO₂H), and isoochracinol II (X = O, Y = CH₂OH).
