Volume 4   New N-protected Aminoaldehydes   The Squarix Newsletter provides you with information about our innovative building blocks, reactive intermediates and screening compounds from our Discovery Chemicals portfolio.   In this issue we present new N-protected Aminoaldehydes especially designed for stereocontrolled organic synthesis.   Featured Products AL001 AL025 AL028 AL032   AL034 AL043 AL044   These compounds are derived from natural and unnatural amino acids and are not commercially available from other manufacturers.   See our website for the full line of building blocks or download the Discovery Chemicals catalogue.   Please find also some selected references from the literature describing interesting applications of N-protected aminoaldehydes. The (E)-alkene dipeptide isostere of Trp-Val was synthesized using the key building block AL044 (Noda et al.). Evans et al. reported an efficient syntheses of L-Statine using L-Leucinal (AL040) as starting material :   AL044     AL040     References   1) M. Noda, T. Ibuka, H. Habashita, and N.
