Functional group interconversions are essential chemical processes enabling synthesis.
In this report, we describe a strategy to convert alkylidenemalononitriles into primary
alcohols in one step. The reaction relies on a choreographed redox process involving
alkylidene reduction, malononitrile oxidation, and acylcyanide reduction where molecular
oxygen and NaBH4 work cooperatively. The method was applied to a variety of carbon skeletons and was
utilized to synthesize complex terpenoid architectures.
