Density functional theory (DFT) predicts that bicyclo[3.1.0]hexatriene ( 2) is more stable than its isomer m-benzyne ( 1). Hess [Eur. J. Org. Chem. (2001) 2185] has argued that experimental findings suggesting 1 can equally or even better be associated with 2. However, high level ...
Explain which isomer is more stable using chair conformation and Newman projection as necessary. Draw the most stable chair form for alpha-D-manopyranose (the alpha anomer of Dmannose in the pyranose form). Draw a Newman projection of the most stable conformation of (2R, 3S)...

Among cruentarenA derivatives, a trans-alkene isomer displayed anticancer activity comparable to cruentarenA itself, targeting three cancer cell lines; further, other analogues also demonstrated potent inhibitory activity. These studies form the cornerstone for the creation of cruentarenA derivatives as ...
The limonene structure has a chiral center, and thus it is found in nature as two enantiomers the (R)- and (S)-limonene. Isomer (R)- has the characteristic smell of oranges, while the (S)- smells like lemons. In oranges, essential oil comprises 95% of (R)-limonene, whereas lemon ...
The oligomeric structure (G)x may be in any isomeric form, whether it is optical isomerism, geometrical isomerism or positional isomerism; it may also represent a mixture of isomers. In formula (II) as defined above, the group R1—O— is linked to G via the anomeric carbon of the ...
