網頁The base name counts the carbon atoms in the rings (8), so the base name is bicyclooctane. The methyl groups are substituents, so the molecule is a dimethylbicyclooctane. ( 4 … 網頁Bicyclic Compounds Nomenclature The two molecules are not identical, therefore they cannot have the same name. Count the number of carbons connecting the bridgeheads. …

We analyzed the results using statistical … 網頁2024年7月20日 · Several days ago I offered a solution to the R/S assignment of the bridgehead carbons of (1R,2S,4R)-2-bromo-2-methylbicyclo[2.2.2]octane 1.During the middle of the night I realized that the method was faulty because the solution would not accommodate the (1S,2R,4S) enantiomer 3 but would rather predict (1R,2R,4R) which …
網頁2004年11月17日 · We first used diversity-oriented synthesis to synthesize the same number (122) of [10.4.0] bicyclic products (B) and their corresponding monocyclic precursors (M). We measured the ability of these compounds to modulate a broad swath of biology using 40 parallel cell-based assays.
網頁Usually, the EWGs are carbonyl or other groups on the dienophile that cause the stereospecificity. In the endo transition states, the p orbitals on the carbonyl groups (or other EWGs) can overlap with the p orbitals on C2 and C3 of the dienophile and provide extra stabilization.
