The redox-neutral dicarbofunctionalization of tri- and tetrasubstituted olefins to form a variety of (hetero)cyclic compounds under photoinduced palladium catalysis is described. This cascade reaction process was used to couple styrenes or acryl amides with a broad range of highly decorated olefins tethered to aryl or alkyl bromides (>50 examples). This procedure enables one or two contiguous all-carbon
Solid-phase synthesis of indol-2-ones (2-oxindoles) by means of aryl radical cyclization of resin-bound N-(2-bromophenyl)acrylamides using Bu3SnH is described. Among various solvents tested, DMF was found to be the best choice for the radical cyclization inducing a reagent concentration effect of the polymer support. The reaction proceeded smoothly under microwave irradiation to give the desired indol-2-ones within a very short reaction time in comparison to conventional thermal heating. In this reaction, various indol-2-ones were synthesized by using commercially available 2-bromoanilines and acryloyl chloride derivatives.
transducers and activators of transcription 5A and 5B (STAT5A and STAT5B) are two closely related STAT family members that are crucial downstream effectors of tyrosine kinase oncoproteins such as FLT3‐ITD in acute myeloid leukemia (AML) and BCR‐ABL in chronic myeloid leukemia (CML). We recently developed and reported the synthesis of a first molecule called 17 f that selectivelyinhibits STAT5 signaling in myeloid

Treatment of the o-bromo-N-acryloylanilides (4) with tri-n-butylstannane leads to the formation of 3-substituted- and 3,3-disubstituted-2-oxindoles (5) in high yield.
