By clicking the Draw Formulas button below a window will open, in which structural formulas for the intermediates may be drawn.

One of the most challenging aspects of learning organic chemistry is devising sequences of reactions that will lead from a designated starting compound to a desired product. This problem concerns the execution of a multistep synthesis. The synthesis shown below requires six steps, and as depicted proceeds in three stages through two stable intermediate compounds A & B. The "Draw Formulas" button opens a window in which you may draw a structural formula for A or B. The reagents required for each step should be entered in the text boxes above and below the arrow for each stage. Subscripted numbers are not possible, so acetic acid is written CH3CO2H (no spaces). Alternatively you may enter names for the reagents (be careful to spell them correctly). Alkoxide or carboxylate salts are assumed to be hydrolyzed. Heat and/or solvents should not be entered. If esters are needed make the ethyl ester. Once the reagents and intermediate (A or B) structure for a given stage are entered, your answers may be checked by pressing the appropriate button (found under each stage). Stage 3 does not have an intermediate. |
