The development of small molecules that inhibitprotein–proteininteractions continues to be a challenge in chemical biology and drug discovery. Herein we report the development of indole‐based fragments that bind in a shallow surface pocket of a humanised surrogate of RAD51. RAD51 is an ATP‐dependent recombinase that plays a key role in the repair of double‐strand DNA breaks. It both self‐associates

The combination of a Pd(0) complex with benzoic acid converts propargylic tryptamines to the corresponding tetrahydro-β-carbolines. The method uses unprotected indoles and affords the desired products with ample functional group tolerance. Detailed modeling studies reveal a close synergy between the organic and metal catalysts, which enables sequential alkyne isomerization, indole C–H activation, and

reaction features an electrophilic “I+” mechanism, which is importantly quite different from and milder than the typical radical-involving process, and can be readily amplified for the totalsynthesis of (+)-WIN64821.

enantioselectivities. Mechanistic studies show that the realization of two sequential single-electron transfer oxidations of the indole derivatives is key, generating the configurationally biased carbocation species while providing the source of stereochemical induction. These results not only provide an efficient synthesis of enantioenriched indoline derivatives, but also offer a novel strategy for further designing
