Abstract:
The Diels-Alder reaction of 3-silyloxy-2-azadiene with formaldehyde has been studied at the B3LYP/6-31G* level of theory and the role played by a Lewis acid evaluated. It is shown that the reaction is preferred when the Lewis acid coordinates to the aldehyde oxygen. This coordination allows for a concerted as well as a stepwise mechanism for the cyclization
