Activation of imide carbonyl group with trifluoromethanesulfonic acid facilitates the intramolecular cyclization of phenethylphthalimides to give a fused isoindoloisoquinolinone skeleton. The first one pot regioselective synthesis of isoindoloisoquinolinone alkaloid (±)-nuevamine has been successfully executed using this methodology.

The total synthesis of a glycoglycerolipid isolate of Meiothermus taiwanensis and its truncated structural analogues is reported. Our synthesis employed DMF-modulated and low-concentration glycosylation reactions for the construction of α- and β-glycosidic bonds in the absence of participating protecting groups. Further simplification of the synthesis was achieved by employing a low-concentrati...

Synthesis 2001, No. 11, 28 08 2001. Article Identifier: 1437-210X,E;2001,0,11,1737,1741,ftx,en;C03601ss.pdf. © Georg Thieme Verlag Stuttgart · New York ISSN 0039-7881 Abstract: A formal catalytic asymmetric synthesis of (+)-biotin was realized. The key steps involve a catalytic, highly enantioselective and quantitative desymmetrization of a meso cyclic anhydride followed by a one-pot chemoselec...

The aesthetics of beautiful molecules has been, and still is, a strong motivation for many chemists. Complex interwoven structures such as catenanes, rotaxanes, and knots are even nowadays appealing because of their interesting topological properties, although their functions as molecular machines have become more and more of the focus of interest. The ability of chemistry to realize the mathem...
