Synthetic design involves two distinct steps: . (1) retrosynthetic analysis and . (2) subsequent translation of the analysis into a "forward direction" synthesis. . In the analysis, the chemist recognizes the functional groups in a molecule and disconnects them proximally by methods corresponding to known and reliable reconnection reactions..
