Synthesis of Two Key Fragments of the Complex Polyhalogenated Marine Meroterpenoid Azamerone
Schnell, Simon D.,Linden, Anthony,Gademann, Karl
, p. 1144 - 1147 (2019)
A concise route toward two advanced fragments in the context of the total synthesis of the unique natural product azamerone is reported. Key synthetic features include the enantioselective synthesis of an epoxysilane and its Lewis-acid-induced cyclization and the installation of the pyridazine ring via a formylation/condensation sequence. This route provides strategic insights into the chemistry of phthalazinediols, facilitating synthetic approaches toward this class of natural products.
Regioselective synthesis of the bridged tricyclic core of Garcinia natural products via intramolecular aryl acrylate cycloadditions
Tisdale, Eric J.,Chowdhury, Chinmay,Vong, Binh G.,Li, Hongmei,Theodorakis, Emmanuel A.
, p. 909 - 912 (2007/10/03)
(equation presented) Two different routes to the tricyclic core of Garcinia-derived natural products are described. The first approach is based on a tandem Claisen/ Diels-Alder rearrangement and delivers the desired lactone 14. The second approach, employ
Synthesis of (S)-4-hydroxy-α-lapachone and biotransformation of some 4-chromanones by Mortierella isabellina ATCC 42613

1-Methoxy-2-naphthol was converted by MOM ether formation, lithiation at C-3, reaction with 3,3-dimethylacryloyl chloride, cyclization, and oxidation using cerium ammonium nitrate to 4-keto-α-lapachone (2,2-dimethyl-4-keto-1-oxa-1,2,3,4-tetrahydroanthra-5
