Molecular Architecture: Advanced Synthesis
Like Duolingo, but for Molecular Architecture: Advanced Synthesis. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.

Key ideas in Molecular Architecture: Advanced Synthesis
- Retrosynthetic arrows (double-lined) signify a conceptual break rather than a physical reaction
- The Michael addition is the forward-reaction logic for 1,5-dicarbonyl disconnections
- Strategic disconnections should maximize the symmetry or simplify the complexity of the resulting fragments
- Heteroatom disconnections (C-X) are prioritized because they often correspond to reliable nucleophilic substitutions
- Breaking rings (especially at fusion points) provides the greatest reduction in topological complexity
- Peripheral chains are removed last as they provide little structural simplification
- Prioritizing strategic bond breakage based on structural simplification rules
- Oxidation of a primary alcohol to a ketone/aldehyde is a tactical FGI to create an alpha-carbon handle
- Synthons represent the polarity (umpolung or natural) required at a specific carbon
- FGIs are used to toggle between electron-withdrawing and electron-donating effects to match the desired synthon polarity
- Reagents must account for stability and solubility that idealized fragments ignore
- The oxidation state of the carbon must be tracked to ensure the FGI is chemically feasible
- Synthetic equivalents like silyl enol ethers provide regioselective control that simple ions cannot
- Distinguishing between theoretical synthons and their practical reagent equivalents.
- Protecting group economy measures the ratio of steps spent on the target vs. steps spent on 'masks'
- FGIs are used to toggle between electron-withdrawing and electron-donating effects
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Molecular Architecture: Advanced Synthesis the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
If you identify a 1,5-dicarbonyl relationship in your target, which forward reaction provides the logical basis for its disconnection?
