Strategic applications is my all time favourite named reaction book. I can't recommend it highly enough for the working chemist, its choice of reactions is far beyond most other books of its type, and the coverage for each reaction is deep, with discovery, mechanism and applications all in a two page spread, linked back to good literature refs. Strat. Apps, along with March (Advanced Organic Chemistry) and Greene and Wutts (Protective Groups in Organic Synthesis) is never far from reach.
These texts are pretty serious stuff, if you end up doing synth org you'll certainly use them. They assume a lot of background knowledge, which might make them hard to get into. Have a look at Clayden etal (Organic Chemistry) if you find the transition a bit daunting, thats a good book for bridging onto more advanced stuff.
