This work investigated a novel photochemical cyclization to form indole derivatives from o-alkynylated F-tagged aniline derivatives, and wide applicability to synthesize differently functionalized indole systems bearing various substituents in the positions N-1, C-2, C-3, C-5 and C-6 was shown. Additionally, this reaction was systematically studied in a kinetic study in an in-house assembled capillary photo-microreactor. Further derivatization of the final F-tagged 3-acylindoles by the cleavage of the perfluorinated chain yielded a library of novel indole-3-carboxylic acid and indole-3-carboxylic acid ester derivatives. A straightforward and efficient four-step methodology for the synthesis of desired indole derivatives with high yields for single steps and the whole sequence was developed. Variing the conditions of single steps showed that all three steps of the reaction route to the cyclization precursors can be performed using the same solvent and base, providing the possibility to conduct this sequence as a continuous-flow without the need for in-line solvent switch or base exchange and without compromises with respect to the selectivity and yields of single steps.

Have you ever wished you could speed up your organic syntheses without losing control of the reaction? Flash Chemistry is a new concept which offers an integrated scheme for fast, controlled organic synthesis. It brings together the generation of highly reactive species and their reactions in Microsystems to enable highly controlled organic syntheses on a preparative scale in timescales of a few seconds or less. Flash Chemistry: Fast Organic Synthesis in microsystems is the first book to describe this exciting new technique, with chapters covering: an introduction to flash chemistry reaction dynamics: how fast is the act of chemical transformation, what is the rate of reaction, and what determines the selectivity of a reaction? examples of why flash chemistry is needed: the rapid construction of chemical libraries, rapid synthesis of radioactive PET probes, and on-demand rapid synthesis in industry the generation of highly reactive species through thermal, microwave, chemical, photochemical, and electrochemical activation microsystems: What are microsystems and how are they made? Why is size so important? What are the characteristic features of microsystems? conduction and control of extremely fast reactions using microsystems applications of flash chemistry in organic synthesis polymer synthesis based on flash chemistry industrial applications of flash chemistry Flash Chemistry: Fast Organic Synthesis in Microsystems is an essential introduction to anyone working in organic synthesis, process chemistry, chemical engineering and physical organic chemistry concerned with fundamental aspects of chemical reactions an d synthesis and the production of organic compounds.
