In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Reactions of sugars and related polyfunctional compounds with amino acids. 2. N-Acylation of 3-amino-1,2-propanediol with amino acids, published in 1982-07-31, which mentions a compound: 82954-65-2, mainly applied to acylation aminopropanediol amino acid; propanediol amino acylation, SDS of cas: 82954-65-2.
Racemic H2NCH2CH(OH)CH2OH was N-acylated with Z-X-OH (Z = PhCH2O2C; X = Ala, Phe, Val, Leu) by 1,1′-carbonyldiimidazole in THF to give Z-X-NHCH2CH(OH)CH2OH (II). In some cases (e.g., X = Ala), one of the 2 diastereoisomers of II spontaneously formed a precipitate, which can be separated The S,S-configuration of II (X = Ala) was established by N-acylating (S)-(aminomethyl)dioxolane (S)-III (R = H) with Z-Ala-OH and cleaving the resulting (S)-III (R = Z-Ala) to give (S,S)-II (X = Ala).
Here is a brief introduction to this compound(82954-65-2)SDS of cas: 82954-65-2, if you want to know about other compounds related to this compound(82954-65-2), you can read my other articles.
