The excision of hydrogen from an aliphatic carbon chain to produce an isolated olefin (desaturation) without over-oxidation is one of the most impressive and powerful biosynthetic transformations for which there are no simple and mild laboratory substitutes. The versatility of olefins and the range of reactions they undergo is unsurpassed in functional group space. Thus, the conversion of a relatively inert aliphatic system to its unsaturated counterpart can open new possibilities in retrosynthesis. In this article, the invention of a directing group to achieve such a transformation under mild, operationally simple, metal-free conditions is outlined. This “portable desaturase” (TzoCl) is a bench-stable, commercial entity (Aldrich, cat # L510092) that is facile to install on alcohol and amine functionalities to ultimately effect remote desaturation, while leaving behind a synthetically useful tosyl group.
