Chemical Structure from Scientific Research

One-step post-synthetic modifications of PyrAtes. OxoPyrAtes and ThioPyrAtes with extended -conjugated systems. Conditions: Iodo-PyrAte (1.0 equiv.), boronic ester (1.1 equiv.), Pd(dppf)Cl2 (0.05 equiv.) and K2CO3 (2.0 equiv.) in THF (0.1 M) at 23 C for 16 h. Was obtained as a mixture of triflate and TFA salts. See Supporting Information for details.
