A novel and practical two-step approach to an intriguing class of imidazo[1,5-a]pyrazines with exocyclic CX (X = CH2, O) bonds is described. The process utilizes a sequential three-component reaction of propargyl amine or aminoester, 1,2-diaza-1,3-di

The curve-fitted Fourier-transform infrared spectrum of linear turn-forming peptides was found to contain an amide I component band near or below 1640 cm −1 , similarly to the IR spectra of cyclic β-turn models. This band, termed β- turn band , i

A facile stereoselective method for the synthesis of γ-substituted, γ-amino acids from α-amino acids was developed. The key step of the procedure is complete reduction of the keto functionality of α-amino acyl Meldrum's acid by sodium acetoxyboro
