9-25 When proposing syntheses, begin by analyzing the target molecule, looking for smaller pieces that can be combined to make the desired compound. This is especially true for targets that have more carbons than the starting materials; immediately, you will know that a carbon-carbon bond forming reaction will be necessary. People who succeed at synthesis know the re a ctions - there is no shortcut. Practice the reactions for each functional group until they become automatic.
