Unfortunately, the program fails completely to crack difficult retrosynthesis problems like challenging heterocycles, regio-selectivity or enantioselectivity issues, things where also experienced chemists could benefit from a little machine help. Chemistry is the scientific discipline involved with compounds composed of atoms, ie elements, and molecules, ie combinations of atoms: their composition. Suppose you’re working an organic chemistry assignment, and you’re asked to propose a mechanism for the conversion of the alcohol shown in the following figure to the alkene shown in the same figure first, you want to identify what kind of mechanism you’re dealing with is it an acid or a .

The synthesis problems you encounter in undergraduate organic chemistry are usually different from those retrosynthetic analysis – the “backward” approach . Guidelines for grignard retrosynthesis the best methodology for preparation of alchols is the grignard (or lithium reagent) addition to an aldehyde or ketone.
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.
