Synthesis of functionally substituted cyanoacetates
摘要:
Some new cyanoacetates were synthesized and characterized. They are precursors for alpha-cyanoacrylates used as rapidly polymerized, cold-hardening adhesives.

The palladium‐catalyzed decarboxylative benzylation of α‐cyano aliphatic carboxylatesalts with benzyl electrophiles was discovered. This reaction exhibits good functional group compatibility and proceeds under relatively mild conditions. A diverse range of quaternary, tertiary and secondary β‐aryl nitriles can be conveniently prepared by this method.

A three-component coupling protocol has been developed for the generation of 3-oxo-3-(hetero)arylpropanenitriles via a carbonylativepalladium-catalyzedα-arylation of tert-butyl 2-cyanoacetates with (hetero)aryl bromides followed by an acid-mediated decarboxylation step. Through the combination of only a stoichiometric loading of carbon monoxide and mild basic reaction conditions such as MgCl2 and

Enantio‐ and regioselective: The intramolecular enantioselective aminofluorination of unactivated olefins was achieved by using a chiral iodo(III) difluoride salt. A highly regioselective aminofluorination of styrenes to access 2‐fluoro‐2‐phenylethanamines was also developed.

transition-metal-free decarboxylative thiolation protocol is reported in which primary, secondary, tertiary (hetero)arylacetates and α-CN substitutedacetates undergo the decarboxylative thiolation smoothly, to deliver a variety of functionalized aryl alkyl sulfides in moderate to excellent yields. Aryl diselenides are also amenable substrates for construction of C–Se bonds under the simple and mild reaction
