An environmentally friendly procedure for Mukaiyama aldol and Mukaiyama–Michael reactions using a catalytic amount of DBU under solvent- and metal-free conditions

Mukaiyama aldol and Mukaiyama–Michael reactions can proceed smoothly in the presence of a catalytic amount of DBU (20% mmol), to afford the corresponding products in moderate to good yields. This solvent- and metal-free approach provides an environmentally friendly procedure for Mukaiyama reactions.
