Herein, we disclose a metal-free novel approach for the synthesis of N-(α-substituted)alkyl sulfoximines/sulfonimidamides via one-pot multicomponent Petasis reactions of aryl boronic acids, ortho-hydroxyarylaldehydes and sulfoximines/sulfonimidamides in moderate to very good yields. The presence of two chiral centres provides a mixture of diastereomers almost in a 1 : 1 ratio, which are separated successfully

novel approach for the synthesis of hitherto unknown α-sulfoximinophosphonate via the Kabachnik–Fieldsreaction of aldehyde, dialkylphosphite and sulfoximine in the presence of InCl3 in THF at 70 °C. α-Sulfoximinophosphonate is synthesized in good yields and its synthetic utilities are proved by functionalizing bromine through the Pd-catalyzed Suzuki–Miyaura cross-coupling reaction and reduction of a nitro
Structural analogues of PFI-1 varying at the sulfur core were prepared, and their activities as BET inhibitors in myeloid cell lines and primary cells from patients with acute myeloid leukemia were studied. Docking calculations followed by molecular dynamics simulations revealed the binding mode of the newly prepared inhibitors, suggesting explanations for the observed high enantiospecificity of the inhibitory activity.
