Useful protected pyrrole derivative which undergoes regioselective electrophilic substitution, e.g. Friedel-Crafts acylation, at the 3-position: Tetrahedron Lett., 22, 4899, 4901 (1981); Synthesis, 353 (1985) (review); J. Org. Chem., 48, 3214 (1983). The phenylsulfonyl group is readily cleaved by alkaline hydrolysis. For acylation followed by reduction as a route to 3-alkylpyrroles, see: J. Org. Chem., 64, 3379 (1999). See also 1-(Triisopropyl­silyl)­pyrrole, L13152.

/n

With a Grignard reagent, e.g. i-PrMgCl, transmetallation occurs at the 2-position, allowing access to 2-substituted derivatives by reaction with electrophiles: Org. Lett., 6, 293 (2004).
