Fluorous mixture synthesis minimizes the effort to synthesize small-molecule libraries by labelling the molecules rather than the reaction vessels. Reactants are labelled with fluorinated tags and products can later be demixed based on the fluorine content. A limit in the number of available tags can be overcome by using binary encoding so that a total of four tags can label uniquely a library of 16 compounds. This strategy, however, means that separation based on fluorine content alone is not possible. Here, we solve this problem by selectively removing one tag after an initial demixing step; a second demixing provides each individual compound. The usefulness of this strategy is demonstrated by the synthesis of a library that contains all 16 diastereomers of the natural products macrosphelides A and E. Macrosphelide D was not in this library, and so its assigned structure was incorrect. We determined its constitution by using NMR spectroscopy and its configuration by synthesizing four candidate stereoisomers. © 2012 Macmillan Publishers Limited. All rights reserved.
