A sustainable one-pot protocol for the synthesis of biobased acrylates has been developed using readily available starting materials under mild conditions. In this method, maleic anhydride reacts with bio-derived alcohols in the presence of catalytic triphenylphosphine to afford the corresponding acrylate derivatives through nucleophilic activation and subsequent dehydration. The transformation proceeds efficiently in a single step without the need for pre-activation of substrates or harsh reagents, providing a straightforward and atom-economic route to valuable acrylate monomers. The methodology demonstrates good functional group tolerance and moderate to good yields, highlighting its potential as a greener and practical approach for the preparation of renewable acrylate building blocks relevant to polymer and materials chemistry.
