Electronically flexible PYA ligands for efficient palladium-catalyzed α-arylation of ketones [PDF]

open access: yes, 2023
Palladium-catalyzed cross-coupling chemistry and in particular ketone α-arylation has been relying on a rather narrow range of supporting ligands with almost no alternatives to phosphines and N-heterocyclic carbenes.

Calcium-Promoted [3+3] Annulation of Morita-Baylis-Hillman Ketones with 2-Aminobenzothiazoles to Construct Pyrimidobenzothiazoles

open access: yes, 2023
The reaction of Morita-Baylis-Hillman (MBH) ketones with 2-aminobenzothiazoles is used to construct new analogues of 4H-benzo [4,5] thiazolo [3,2-a] pyrimidine. MBH ketone provides a desirable reactivity with significant outcomes.
