Dithioacetal Exchange: A New Reversible Reaction for Dynamic Combinatorial Chemistry

Abstract

Reversibility of dithioacetal bond formation is reported under acidic mild conditions. Its utility for dynamic combinatorial chemistry was explored by combining it with orthogonal disulfide exchange. In such a setup, thiols are positioned at the intersection of both chemistries, constituting a connecting node between temporally separated networks. In reverse: Reversibility of dithioacetal bond formation is reported under acidic mild conditions (see figure). Its utility for dynamic combinatorial chemistry was explored by combining it with orthogonal disulfide exchange. In such a setup, thiols are positioned at the intersection of both chemistries, constituting a connecting node between temporally separated networks.
