Demethylative Lactonization Provides a Shortcut to High-Yielding Syntheses of Lamellarins
De Koning, Charles B.,Klintworth, Robin,Michael, Joseph P.
, (2020/01/31)
Modular gram-scale syntheses of the trimethyl ethers of lamellarins G (6) and D (7) were achieved from readily accessible precursors in the highest overall yields reported to date (6, six steps, 82%; 7, seven steps, 86%). A novel demethylative lactonizati

A new synthetic route was developed for the preparation of natural products cryptostyline I, II, III and 1-phenyl-6,7-dimethoxy-2-methyl-1,2,3,4-tetrahydroisoquinoline. The Liebeskind-Srogl palladium-catalyzed carbon-carbon cross-coupling protocol was use
Reactions of 1,2,3,4-Tetrahydroisoquinoline Derivatives with Sulfur

1,2,3,4-Tetrahydroisoquinolines react with sulfur in pyridine to give two different types of products, depending on the structure of the starting compounds. 1-Substituted derivatives 1 undergo partial dehydrogenation with formation of the corresponding 3,4-dihydroisoquinolines 3. 1,2,3,4-Tetrahydroisoquinolines 5 bearing no substituent in 1-position yield the 3,4-dihydro-1(2H)isoquinolinethiones 6, comprising a new and simple synthesis of compounds 6.
