Streamlined biomimetic synthesis of paracaseolide A via aerobic oxidation of a 2-silyloxyfuran
摘要:
A simple, bioinspired synthesis of the naturally occurring Cdc25B inhibitor paracaseolide A is reported. Key steps include: (i) an aerobic oxidation of a 2-silyloxyfuran to the corresponding silyl ketoester, and (ii) the preparation of the former intermediate by silylation of an alpha-alkylidenebutenolide. Both of these high-yielding transformations are unprecedented. (C) 2014 Elsevier Ltd. All rights reserved.
