Abstract
Acrylates are well known electrophilic alkenes having multitude of applications in organic synthesis. They are very good acceptors in Michael addition reactions and are good enophile/dienophile/dipolarophile partners in cycloaddition reactions. Replacing the β-alkyl/aryl groups in acrylates by a silicon group would be interesting. In addition to the conventional reactions displayed by acrylates, β-silylacrylates (β-SAs) can show reactivity specifically related to the silicon group. Many conventional organic reactions such as hydrodimerization, organocatalytic asymmetric Michael additions, inter- and intra-molecular Diels–Alder reactions, and asymmetric 1,3-dipolar cycloadditions have been used to generate the complex chemical entities from β-SAs. Some of the reaction outcomes were vastly influenced by the silicon substituent. This review describes the practical synthesis β-SAs and their use as starting point in complex molecule generation including total synthesis of some natural products/bioactive molecules.
期刊介绍:
Helvetica Chimica Acta, founded by the Swiss Chemical Society in 1917, is a monthly multidisciplinary journal dedicated to the dissemination of knowledge in all disciplines of chemistry (organic, inorganic, physical, technical, theoretical and analytical chemistry) as well as research at the interface with other sciences, where molecular aspects are key to the findings. Helvetica Chimica Acta is committed to the publication of original, high quality papers at the frontier of scientific research. All contributions will be peer reviewed with the highest possible standards and published within 3 months of receipt, with no restriction on the length of the papers and in full color.
