Synthesis towards complex bridged alkaloids derived from diketopiperazines: a cationic cascade approach to stephacidins, paraherquamides and related systems
Pichowicz, Mark,Simpkins, Nigel S.,Blake, Alexander J.,Wilson, Claire
, p. 8413 - 8417 (2006)
Regioselective enolate formation, followed by stereoselective electrophilic quenching of unsymmetrical proline-derived diketopiperazines (DKPs), enabled the synthesis of variously substituted DKPs, including one substrate which could be further substitute
Studies towards complex bridged alkaloids: regio- and stereocontrolled enolate chemistry of 2,5-diketopiperazines
Pichowicz, Mark,Simpkins, Nigel S.,Blake, Alexander J.,Wilson, Claire
, p. 3713 - 3735 (2008/09/21)
The substitution of symmetrical N-protected diketopiperazines (DKPs) via enolate intermediates has been studied. The enolate reactions were highly diastereocontrolled, leading to enantiopure DKP products if chiral amino acid precursors were employed, and
Chemoselective oxidative debenzylation of N,N-dibenzylamines

Tertiary amines incorporating two N-benzyl substituents are readily mono-debenzylated with CAN or DDQ. An N,N-dibenzyl derivative of a dienylamine with a homoallylic C-N bond is smoothly deblocked by DDQ as well, whereas CAN leads to fragmentation in this case.
