The present invention provides convergent processes for preparing beta-elemene, and analogues thereof. Also provided are analogues related to beta-elemene and intermediates useful for preparing the same. The present invention further provides novel compositions based on analogues of beta-elemene and methods for the treatment of cancer, such as brain tumor, lung cancer, colorectal cancer, gastric intestional cancer, and stomach cancer.
Abstract The synthesis of the pseudopterosin A–F aglycone from 3-methylcatechol features (a) the use of asymmetric Ireland–Claisen and aryl Claisen rearrangements to install three of the four stereocentres present in the molecule and (b) an A→AB→ABC annulation strategy using ring-closing metathesis and cationic cyclisation reactions as the key steps. The synthesis of the pseudopterosin A–F aglycone from 3-methylcatechol
