substituted β‐functionalised styrenes by microwave‐assisted olefin cross‐metathesis (CM) is described. This method can be also employed in the synthesis of β‐deuterated α,β‐unsaturated sulfones from inexpensive allylbenzenes, though unprecedented one‐pot isomerisation/deuteration/cross‐metathesis sequence. One of such obtained CM products has been utilised in a new scalable synthesis of Apremilast
The present invention relates to a process for providing a chiral β-hydroxysulfone compound, an intermediate useful in the synthesis of the isoindoline-based compound apremilast.
