and 3 respectively, have been prepared in a convergent manner by two relatedroutes. The superior one involves C–H functionalization of the relevant 5-methoxyindole at C-7 using Hartwig’s protocol and thus forming the corresponding borolated indole that could be coupled with the requisite 2-bromobenzoate to deliver the title naturalproducts. Single crystal X-ray analyses of the synthetically derived
