A. Denicola et al., INTRAMOLECULAR ALKYLATION OF CARBOXYLIC-ACIDS - APPLICATION TO THE SYNTHESIS OF BOC-PROTECTED CYCLIC AMINO-ACIDS, Journal of the Chemical Society, Chemical Communications, (7), 1994, pp. 879-880
A new synthesis of Boc-protected cyclic amino acids is described as an
application of an unreported method of lithium diisopropylamide-induc
ed cyclisation of omega-chloro carboxylic acids containing a protected
amine function in the chain.
