| 520 | _aGranting that we know the chemistry of the individual steps, how do we go about planning a route to more complicated compounds-alcohols, say? In almost every organic synthesis it is best to begin with the molecule we want the target molecule-and work backwards from it. There are relatively few ways to make a complicated alco-hol, for example; there are relatively few ways to make a Grignard reagent or an alde-hyde or ketone; and so on back to our ultimate starting materials. On the other hand. our starting materials can undergo so many different reactions that, if we go at the prob-lem the other way around, we find a bewildering number of paths, few of which take us where we want to go. We try to limit a synthesis to as few steps as possible, but nevertheless do not sacrifice purity for time. To avoid a rearrangement in the preparation of an alkene, for example, we take two steps via the halide rather than the single step of dehydration. | ||
