  An efficient protocol for the benzylation or allylation of amides using the corresponding benzyl or allyl chlorides as electrophiles under basic conditions with commercially available 5 mol % of [Cu(OH)TMEDA]2Cl2 as catalyst was developed. Under these conditions, unprotected amino acids were benzylated without any racemization.

  Brønsted acid-catalyzed dehydration of 3-alkyl-3-hydroxyisoindolin-1-ones is discussed. The reaction is efficiently catalyzed by methanesulfonic acid in acetonitrile and provides the corresponding 3-methyleneisoindolin-1-ones. The E/Z stereochemistry around the exocyclic double bond is in strong correlation with the size of the N-substituent. Selective formation of only one stereoisomer can be controlled
