The search for novel chemical architectures displaying improved biological properties is a never-ending synthetic challenge. In this context many new test structures are often conceived by selecting and replicating specific design elements from naturally occurring molecules and displaying them in an alternative format by way of a new chemical assembly. Constructing these newly designed compounds can be a timely and expensive process especially when a large quantity of the target material is required for physiochemical and property testing. To permit easier scale-up and safer working practice, many chemical researchers are employing flow chemistry approaches to aid in their synthesis challenges. The preparation of a key spirocyclic lactone using flow-based reaction processing techniques is reported.
