Abstract The novel amino acid 2,4-diamino-3-methylbutanoic acid has been identified in nodules formed by two strains of Rhizobium bacteria on Lotustenuis roots. Retention time measurements on a Chirasil-Val capillary column suggest it is present as the (2 R ,3 S )-enantiomer. Several isomeric diamino acids were synthesized for comparative studies.
摘要 2,4-diamino-3-methylbutanoic acid 是一种新型氨基酸 2,4-diamino-3-methylbutanoic acid,在细莲根上由两株根瘤菌形成的根瘤中被鉴定出来。Chirasil-Val 毛细管柱上的保留时间测量表明它以 (2 R ,3 S )-对映异构体形式存在。合成了几种异构二氨基酸用于比较研究。

The present invention concerns new stable compositions of 1-Z-bromoalk-1-ene compounds of general formula (A). These compositions are characterized in that they also comprise either at least one cyclic ether compound comprising between 4 and 6 carbon atoms, or at least one ether of general formula (B) in which R
1
and R
2
are identical or different and selected from the group consisting of: a linear or branched alkyl group containing 1 to 8 carbon atoms.
