Abstract:
Two new acetophenone derivatives and a new sesquiterpene, along with four known acetophenone compounds, were isolated from the roots of Euphorbia ebracteolata. The structures of the new compounds were identified as 2,2',4,4'-tetrahydroxy-6,6'-dimethoxy-3,3'-dimethyl-7,5'-bisacetophenone, 2,4-dihydroxy-6-methoxy-3-methylacetophenone 4-O-alpha-L-arabinofuranosyl-(1-->6)-beta- D-glucopyranoside and decahydro-1a,4a,7,7-tetramethyl-1H-cycloprop[e]azulene-2,5-diol (1a R,2 R,4a S,5 S,7a R,7b R) using 1D and 2D NMR spectroscopy and X-ray crystallography.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.

Structure and Nomenclature of Ethers
Ethers are organic compounds with an ether functional group which is characterized by an oxygen atom connected to two — identical or different — alkyl, aryl, or vinyl groups. The C–O–C linkage in dimethyl ether — the simplest ether — has an approximately tetrahedral bond angle of 110.3 degrees. The oxygen atom is sp3- hybridized, with the C–O distance being about 140 pm.
Classification of Ethers
Based on their attached substituent groups, ethers can be classified into two...
