Our synthetic efforts towards an iNOS (inducible isoform of the nitric oxide synthase) inhibitor led us to the relatively unexplored field of generating and controlling the reactivity of chiral, unsymmetrical thiiranium species. We found that product regiochemistry depends on a tunable equilibrium, the understanding of which proved pivotal in defining a new route to a drug substance. The development...
A high yielding and selective method for producing methyl 5-amino-2H-1-benzopyran-8-carboxylate derivatives via gold(I)-catalysed intramolecular alkyne hydroarylation has been developed.
