  A multicomponent reaction between H-2, CO, an unsaturated carboxylic acid derivative, and binucleophiles has been discovered, This process represents a combination of diversity-oriented synthesis and multicomponent reactions including amidation and hydroformylation, followed by nucleophilic addition to an N-acyliminium ion allowing the generation of six new bonds. Using pi-nucleophiles, the sequence turns into a multicomponent Pictet-Spengler reaction.

  A multicomponent reaction that employs an unsaturated carboxylic acid, a 1,2 or 1,3 amino alcohol and gaseous CO and H-2 has been discovered. Thus, hydrocarbonylation of the carboxylic acid double bond generates a linear aldehyde, that is, immediately transformed into an oxazolidine. Further microwave assisted intramolecular lactamization delivers oxazolopiperidines with the generation of six new bonds in a one-pot single step. Bicylic, tricyclic, tetracyclic, and spirocyclic oxazolopiperidines can be prepared in good yields and acceptable stereoselection. The reaction did not occur under conventional heating even at higher temperature and pressure and for longer time, showing that microwave heating is indispensable to the process.
