C-H activation of indole-derivatives catalysed by Pd-nanobiohybrids under mild conditions [PDF]
, 2022 A mild C-H activation of protected L-tryptophan catalyzed by palladium bionanohybrids was developed. Several Pd-biohybrids were synthesized and the influence of temperature or different enzymes as scaffolds were investigated.
