N-alkynylation of pyrrole and a gold-catalyzed spiroketalization were key steps in the total synthesis of the pyrrole spiroketal alkaloid shensongine A. The preparation of this alkaloid is concise and amenable to the rapid synthesis of a diverse library of compounds. A copper-catalyzed N-alkynylation of pyrrole and a gold-catalyzed spiroketalization were key steps in the total synthesis of the pyrrole spiroketal

cross-coupling of alkynyl bromides with pyrroles, reveals that the use of the phenanthroline ligand 4,7-dimethoxy-1,10-phenanthroline affords a range of ynpyrroles in good to moderate yields. Furthermore, the utility of these ynpyrroles is demonstrated in the preparation of a series of pyrrolo[2,1-c][1,4]oxazin-1-ones and a formal total synthesis of the pyrrole natural product peramine. Screening of a variety of
