The marine algaLaurencia brongniartii produces thiobromoindoles and 3,3′-bisindoles, structural motifs rare outside this genus. A gram scale synthesis of methyl 4,6-dibromoindole-3-carboxylate followed by facile hydrolysis-decarboxylation provided a scalable route to glossobalol (4,6-dibromoindole). Methylthiolation of glossobalol followed by a [1], [2]-sulfide shift gave the natural product 2-(m
