Natural product libraries from microbial extracts

Some reactions afford mixtures of products. Mixtures include diastereomers, such as endo and exo products (10.1 and 10.2) of a Diels-Alder cycloaddition, and regioisomers, such as ortho and para products (10.3 and 10.4) from an electrophilic aromatic substitution (Scheme 10.1). Even a reaction that forms products as subtly similar as enantiomers is technically a mixture of products. Isomeric mixtures violate the spirit of one compound, one well in combinatorial chemistry. Isomeric mixtures, however, are often unavoidable and therefore tolerated in compound libraries. Mixtures are also tolerated in libraries of compounds that have been derived from natural sources. Examples include extracts from finely ground vegetation and microbial broths. [Pg.248]
