Cyclic acetals (dioxolanes) are useful protecting groups in organic synthesis but they can also be converted to other useful functional groups. Bismuth triflate is an efficient catalyst for the allylation of cyclic acetals followed by in situ derivatization of the product with acid anhydrides. Such multicomponent reactions save steps and work up after each step associated with a multi-step synthesis. Bismuth compounds are attractive as catalysts because of their remarkably low toxicity and ease of handling. The results of this study will be presented.
