The oxime has its OH group anti to the ring junction to minimize steric hindranceas oxime formation is under thermodynamic control (Chapter 14).ORitter reactionThe experiments also provide stereochemical evidence that a carbocation is an intermediate inboth reactions. Both starting materials are cis-...
X must be a better leaving group than Y (otherwise the reverse reaction would take place) 2. Y must be a strong enough nucleophile to attack RCOX 3. RCOX must be a good enough electrophile to react with Y– R O X R O Y XY pKaHis a guide to nucleophilicity We have seen how pKa...
Good luck. • Scott Thompson The best way to do well in Organic Chemistry is to really try to understand the underlying concepts of how and why things react the way that they do. It is much easier to remember a reaction or mechanism if you have a good understanding of why it is ...

The early chemistry chapters feature carbonyl group reactions because addition to carbonyl groups is probably the easiest reaction to understand. Thereafter the chemistry develops in a logical sequence but chapters on spectroscopy, stereochemistry etc are interspersed among those dealing with chemical ...
Aza-heterocycles with rings of more than 6 members are underrepresented in medicinal chemistry owing to challenges with their synthesis. Now, the conversion of 5- and 6-membered saturated cyclic amines into 7- and 8-membered aza-heterocycles can be achieved via a ring expansion cascade reaction....
