Đặt câu có từ "alloisoleucine"
1. The nitrogen atom at C-2 of L-alloisoleucine is shown to be retained.
2. Coronamic acid is shown to be derived from L-isoleucine via the intermediacy of L-alloisoleucine.
3. Key words: hydroxyglycine, glyoxylic acid, allylboronates, α-amino acids, allylglycines, isoleucine, alloisoleucine, stereoselective reactions, isomerization, 2-aza (azonia) Cope rearrangement.
4. For instance, the reactions with (E)- and (Z)-crotylboronates afforded the corresponding anti- and syn-crotylated products (isoleucine and alloisoleucine after hydrogenation) with high diastereoselectivity, respectively.
5. This observation indicates that the cyclization of L-alloisoleucine to coronamic acid can occur before formation of the amide bond between coronafacic acid and coronamic acid.
6. The method comprises culturing a bacterium or a fungus in a medium that contains isoleucine, L-isoleucine, D-isoleucine, alloisoleucine, or a racemic or non-racemic mixture thereof.
7. represent a residue selected from the group of the following L- or D-amino acids: alanine, alloisoleucine, cyclohexyl-glycine, phenyl-alanine, glutamine, histidine, isoleucine, leucine, lysine, methionine, pipecolic acid, proline, tyrosine and valine; and Q¿2?-Q¿4?
8. Examination of the mechanism of the cyclization of L-alloisoleucine to coronamic acid revealed that the formation of the cyclopropane ring takes place with the removal of only two hydrogen atoms from the amino acid, one at C-2 and the other at C-6.
9. A novel screening method using an automated flow injection electrospray ionization tandem mass spectrometry system is proposed for the simultaneous determination of five nonprotein amino acids (β-alanine, alloisoleucine, ornithine, citrulline, pyroglutamic acid) and three Betaines (glycine betaine, trigonelline, proline betaine) after derivatization with butanolic HCl
