pyridinium iodides 6 were solvolyzed in water and in aqueous solvents, as well as under micellar conditions. All esters show in each of the solvents normal values of secondary α-deuterium isotope effects (kHkD = 1.17–1.23). Also in comparison to saturated analogues the investigated esters show a lower solvolytic reactivity. On the basis of these results it was concluded that the solvolysis proceeds via

fragment 1 in BMS-986251 was synthesized starting from Hagemann’s ester 2 in 7 steps and 5 isolations. The route is highlighted by a dynamic kinetic resolution (DKR), a telescoped enol nonaflation followed by a palladium-catalyzed carbonylation, and a rhodium-catalyzed directed diastereoselective olefin hydrogenation. The optimized process was demonstrated on 1 kg scale, with an overall 51% yield and >99%
