Strategy for Traceless Codrug Delivery with Platinum(IV) Prodrug Complexes Using Self-Immolative Linkers
Lee, Violet Eng Yee,Lim, Zhi Chiaw,Chew, Suet Li,Ang, Wee Han
, p. 1823 - 1831 (2021)
A common challenge in Pt(IV) prodrug design is the limited repertoire of linkers available to connect the Pt(IV) scaffold with the bioactive payload. The commonly employed linkers are either too stable, leading to a linker artifact on the payload upon rel

A versatile and DES-compatible bipyridine palladium complex has been developed as a general pre-catalyst for different cross-coupling reactions (Hiyama, Suzuki-Miyaura, Heck-Mizoroki and Sonogashira) in deep eutectic solvents. Hydrogen bond capacity of the ligand allows to keep the excellent level of results previously obtained in classical organic solvents. Palladium pre-catalyst showed a high catalytic activity for many cross-coupling reactions, demonstrating a great versatility and applicability. Also, this methodology employs sustainable solvents as a reaction medium and highlights the potential of DES as alternative solvents in organometallic catalysis. The catalyst and DES were easily and successfully recycled. The formation of PdNPs in DES has been confirmed by TEM and XPS analysis and their role as catalyst by mercury test. The dynamic coordination of bipyridine-type ligand in the palladium complex formation has been studied via UV/Vis. (Figure presented.).

An unprecedented deformylative coupling of salicylaldehydes to acrylates and acrylamides under Rh-catalyzed conditions is reported. These deformylative couplings afforded o-hydroxycinnamates and o-hydroxycinnamamides with broad functional group tolerance and high chemoselectivity under milder reaction conditions.
