Abstract:
THE TITLE SESQUITERPENE [SYSTEMATIC NAME: 6-methoxy-10-methyl-7-(propan-2-yl)-2-oxatricyclo[6.3.1.0(4,12)]dodeca-1(11),4,6,8(12),9-pentaen-5-ol], C(16)H(18)O(3), was isolated from pathogen-infected stele tissue of Gossypium barbadense. There are two mol-ecules in the asymmetric unit and the dihedral angle between their naphtho-furan systems is 86.48 (2)°. In the crystal, O-H⋯O hydrogen bonds between the hy-droxy groups and etheric O atoms link the mol-ecules into centrosymmetric tetra-mers. These tetra-mers are assembled into (010) layers via stacking inter-actions between the naphtho-furan systems [inter-planar distance 3.473 (3) Å] and short C-H⋯O contacts.

Hypoxia
Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...

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...
