General Description

Azuleno[4,5-b]furan-2(3H)-one,3a,4,5,6,6a,7,9a,9b-octahydro-3,9-dimethyl-6-methylene-, (3S,3aS,6aR,9aR,9bS)- is a chemical substance with a complex structure comprising multiple carbon-hydrogen bonds, and it is chiral in nature as it has multiple stereocenters. It belongs to the class of organic compounds known as azulenones, which are characterized by a five-membered furan ring attached to an azulene moiety. The specific details about its properties, applications or biological activities are not readily available, indicating that it may not be widely studied or utilized in scientific or industrial processes.

A biomimetic total synthesis of (+)-ainsliadimer A

Figure Presented. A protecting group free and biomimetic total synthesis of (+)-ainsliadimer A has been accomplished in 14 steps from α-santonin. The synthesis relies on a hydrogen bonding promoted [4 + 2]-hetero-Diels-Alder dimerization to afford the key homodimer intermediate, which demonstrates the feasibility of using nonenzymatic conditions to achieve the proposed biosynthesis.

Regio- and stereoselective oxyfunctionalization at C-1 and C-5 in sesquiterpene guaianolides

The regio- and stereoselective functionalization at C-1 and C-5 positions in a guaiane skeleton by allylic hydroxylation are described. The stereochemistry of the resulting compounds are identical to those of the majority of natural 1- and 5-hydroxy-guaianolides.
