The selective deoxygenation of polyols is a frontier in our ability to harness the stereochemical and structural complexity of natural and synthetic feedstocks. Herein, we describe a highly active and selective boron‐based catalytic system for the selective deoxygenation of terminal 1,2‐diols at the primary position, a process that is enabled by the transient formation of a cyclicsiloxane. The method
A process for the preparation of indanones of the formula II from indanones of the formula I or of indanones of the formula IIa from indanones of the formula Ia
1
comprises reacting an indanone of the formula I or Ia with a coupling component.
