Hirose, Yuta published the artcileStereoselective synthesis of the A-ring of armatol A from a bromo-substituted chiral building block based on Ireland-Claisen rearrangement and ring-closing olefin metathesis, Product Details of C9H22OSi, the publication is Heterocycles (2015), 91(1), 76-103, database is CAplus.
The stereoselective synthesis of the A-ring (I) of armatol A, a natural polycyclic ether triterpene from the red alga Chondria armata, was achieved in a non-biomimetic way. The synthesis employed Ireland-Claisen rearrangement of an ester, prepared from a bromo-substituted chiral building block, for the construction of C6 and C7 stereocenters and a relay ring-closing olefin metathesis for the seven-membered ring formation.
