Retrosynthesis or retrosynthetic analysis is a strategy for planning an organic synthesis by disconnecting a target molecule into precursor materials this steps are repeated until available starting materials are reached.
Designing organic synthesis ch-588: organic synthesis course slides instructor: krishna p kaliappan role of synthetic chemistry synthetic chemistry biology medicine organic synthesis-means the same as synthetic organic chemistry total synthesis: the chemical synthesis of a molecule from a. Retrosynthesis means planning a synthesis backwards, by starting at the product, the target and taking it back a step at a time to simple, available starting materials or precursors in general students dislike these problems because it requires thinking backwards, good problem solving skills, and a good knowledge of their organic reactions. Department of organic chemistry organic synthesis the ideal synthesis retrosynthetic (or antithetic) analysis is a problem solving technique for transforming the structure of a synthetic target molecule (tgt) to a sequence of progressively retrosynthetic analysis or retrosynthesis the process of mentally breaking down a molecule into a.
