The chem. investigation of whole plants Piper boehmeriifolium (Miq.) Wall. ex C. DC. led to the isolation of 22 compounds, including two lignans (1-2), sixteen amide alkaloids (3-18), one diterpene (19), two monoterpenes (20-21), and one phenylpropanoid (22). Their structures were elucidated by extensive spectroscopic analyses including NMR, MS, and by comparison with the literature. Compounds 1-2, 6-7, 11-12, 14, and 17-22 were firstly isolated from P. boehmeriifolium, while compounds 2, and 19-20 were isolated from Piper genus for the first time. The chemotaxonomic significance of these isolated compounds is discussed. This study involved multiple reactions and reactants, such as (2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7COA of Formula: C14H25NO).
(2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium.COA of Formula: C14H25NO
