photoredox-mediated conditions using a series of amino acid derivatives gave (3–8, 19, and 34) in 30–74% yield and isomer ratios in the range 6.7:1 to >50:1. The latter methods gave overall yields similar to that of the deprotonation approach, but were shorter and more amenable to scale-up. In particular, N-Boc analogue 8 was obtained in a singlestep. The amidomethylations of another six 3-fluoropyridines under the
Metal chelating compounds of formula (I) are provided: or tautomers thereof or a pharmaceutically acceptable salt of either characterised in that R1 is selected from the group H and C1-6 alkyl R2, R4 and R5 are independently selected from the group H, C1-6 alkyl, Cl, F, -CHF2, CF3, -C(O)CF3, -CH(OH)CF3 and R6 R3 is selected from the group H, C1-6 alkyl and C1-6 acyl R6 is a group -C(O)-N(R7)(R8) R7 is selected from H and C1-6 alkyl and R8 is selected from H, C1-6 alkyl and a group -CH(R9CO)-N(R10XR11 ). R9 and R10 are independently selected from H, C1-6 alkyl and C1-10 aralkyl and R11 is selected from H and C1-6 alkyl, or R10 and R11 together with the nitrogen to which they are bonded form a 3-8 membered heterocyclic ring wherein at least one of R2, R4 and R5 is F. The compounds of the invention have reduced susceptibility to glucuronidation and microsomal oxidation as compared to current clinical compounds of the same class but in preferred forms have lower molecular weight and have blood brain barrier permeability.
rhodium-catalysed dearomatization–hydrogenation of fluoropyridine precursors. This strategy enables the formation of a plethora of substituted all-cis-(multi)fluorinated piperidines in a highly diastereoselective fashion through pyridine dearomatization followed by complete saturation of the resulting intermediates by hydrogenation. Fluorinated piperidines with defined axial/equatorial orientation of fluorine
