Intramolecular Heck reaction with substrates possessing an allylic alcohol moiety
摘要:
In this paper we report our investigation on a series of palladium catalysed cyclisations with substrates possessing an allylic alcohol moiety. This methodology provides a good approach to a wide variety of functionalised 5 or 6 membered carbo- or heterocycles. We also demonstrate that it is possible to combine an alkylation and a cyclisation process using the same palladium catalyst system.

highly practical and step‐economic α,β‐dehydrogenation of carboxylic acids via enediolates is reported through the use of allyl‐palladium catalysis. Dianions underwent smooth dehydrogenation when generated using Zn(TMP)2⋅2 LiCl as a base in the presence of excess ZnCl2, thus avoiding the typical decarboxylation pathway of these substrates. Direct access to 2‐enoic acids allows derivatization by numerous
