A practical method for the nucleophilic substitution (SN) of alcohols furnishing alkyl chlorides, bromides, and iodides under stereochemical inversion in high catalytic efficacy is introduced. The fusion of diethylcyclopropenone as a simple Lewis base organocatalyst and benzoyl chloride as a reagent allows notable turnover numbers up to 100. Moreover, the use of plain acetyl chloride as a stoichiometric promotor in an invertive SN-type transformation is demonstrated for the first time. The operationally straightforward protocol exhibits high levels of stereoselectivity and scalability and tolerates a variety of functional groups.

Meeting the challenge: A reliable and modular reaction sequence has been developed for the synthesis of the challenging tubulysin framework. This route allows preparation of hundreds of milligrams of the stereochemically pure tetrapeptides (see picture), which are produced in small amounts by two different species of myxobacteria. Thus, full biological evaluation of the tubulysins and their analogues is now a real possibility. (Chemical Equation Presented).
