Reaction rule retrosynthesis

WebThe basic idea of retrosynthesis problems is that you have a product in mind and need to figure out how to make it from basic starting materials. Retrosynthesis problems require … WebApr 11, 2024 · Further, multi-step retrosynthesis (when identified reactants can’t be purchased themselves and need to be further synthesized retrosynthetically) makes the process even more complicated. A template-based approach has been a widely used method for retrosynthesis planning where predefined rules are created to guide a reaction.

Voiceover: We've done a lot of aldol condensations, and in particular, we've looked at the mechanism in great detail. In this video, we're going to think about doing things in reverse. So we're going to start with a retro aldol reaction and see how that way of thinking can apply to retro synthesis.
