Typical Procedure (Given for 6a, To a solution of 124 mg of o-nitrobenzaldehyde 2a (0.82 mmol, 1 equiv)and 60 mg of butylamine 3a (0.82 mmol, 1 equiv) in MeOH (800 μL, 1 M) were added 157 mg of homoveratryl isocyanide(4a, 0.82 mmol,-1 equiv) and 57 μL of pyruvic acid (1a, 0.82 mmol, 1 equiv) under inert argon atmosphere. The mixture was then stirred at r.t. during 2 h. After concentration under reduced pressure, the crude product was dissolved in 4 mL of TFA (0.2 M) and stirred at r.t. for 1 h. Flash chromatography (50-100% Et2O-petroleum ether gradient) afforded the desired diketopiperazine in a 69% overall yield as a mixture of two diastereomers in a 1:1.2 ratio. Spectroscopic Data for DKP 6a: Major diastereomer: 1H NMR (400 MHz, CDCl3, δ, 7.94 (d, J, 7.8 Hz, 1 H, 7.78 (s, 1 H, 7.40 (dt, J, 3.8, 7.6 Hz, 2 H, 6.74 (d, J, 7.6 Hz, 1 H, 6.55 (s, 1 H, 6.25 (s, 1 H, 4.69 q, J, 7.8 H
