note
-
This protocol was developed using temperature-controlled MW heating methods by sandwiching a fiber optic temperature probe between two Weflon plates (one with a groove that fit the probe), ramping to a desired temperature using MW irradiation, and then holding at that temperature for a specified amount of time. The average wattages obtained during the ramp and hold times were then used in SPOT reactions to reproduce these heating curves.

note
-
The isocyanide was not premixed with the other components, to avoid formation of the Passerini 3CR product, and was applied to the support after the aldehyde/carboxylic acid mixture. We attribute the improved product purity to better mixing and the order of addition.
