摘要:

AbstractThe novel amino acid (±)‐β‐(2‐amino‐1,3‐selenazol‐4‐yl)alanine4awas prepared from selenourea and 1,3‐dichloropropan‐2‐one via a four‐step synthetic sequence. Nuclear magnetic resonance analysis indicated a downfield chemical shift of δ 0.29 to 0.30 and δ 0.57 for the C5‐proton of the protonated 2‐amino‐and 2‐acetamido‐1,3‐selenazoles respectively compared with the analogous thiazoles. The infrared spectra of the selenazole and corresponding thiazo
