This invention is directed to processes for the preparation of a compound of the formula I or salt thereof,
that is useful as a tryptase inhibitor, to intermediates useful in the preparation of such a compound, to processes for the preparation of such intermediates, and to the use of such intermediates for the preparation of such a compound.
of the library gave some excellent catalysts for regioselectivehydroformylation of β,γ‐unsaturatedcarboxylicacids. A terminal alkene, but‐3‐enoic acid, was hydroformylated with a linear/branched (l/b) regioselectivity up to 41. An internal alkene, pent‐3‐enoic acid was hydroformylated with regioselectivity up to 18:1. Further substrate selectivity (e.g., acid vs. methyl ester) and reaction site
