  Synthetic Versatility in C–H Oxidation: A Rapid Approach to Differentiated Diols and Pyrans from Simple Olefins

  摘要：

  Conventionally, C-H oxidation reactions are used to install functional groups. The use of C-H oxidation to transform simple starting materials into highly versatile intermediates, which enable rapid access to a range of complex target structures, is a new area with tremendous potential in synthesis. Herein we report a Pd(II)/sulfoxide-catalyzed allylic C-H oxidation to form anti-1,4-dioxan-2-ones from homoallylic oxygenates. These versatile building blocks are rapidly elaborated to differentiated syn-1,2-diols, stereo-defined amino-polyols, and syn-pyrans, structures ubiquitous in medicinally important complex molecules found in Nature. We also demonstrate that a C-H oxidation approach to the synthesis of these motifs is orthogonal and complementary to other state-of-the-art methods.
