Enantioselective sulfonylation reactions mediated by a tetrapeptide catalyst.

ABSTRACT: While Nature excels at performing selective modifications of complex polyfunctional molecules through the use of tailoring enzymes, synthetic chemistry has lagged behind in this regard. In prior work, we have applied a biomimetic approach to this problem, developing small peptides to achieve various group transfer reactions on polyol substrates with high enantio- or regioselectivity. The utility of sulfonates as synthetic building blocks and the scarcity of direct, selective methods for their preparation prompted our investigation into this area. In this article we report the development of a pi-methyl histidine-based tetrameric peptide that effects the desymmetrization of meso-1,3-diols through enantioselective (mono)sulfonylation. The catalyst exhibits structural similarities to another
