problem-statement

SOLUTION:

reactions-alkylation-enolates-01

Part a) has a low yield due to polyalkylations. In section c) an intramolecular alkylation occurs, using a highly hindered base (LDA) that will have serious difficulties in deprotonating the right alpha carbon, most likely following alternative paths such as the one indicated below.
