Asymmetric Synthesis of Highly Functionalized Tetrahydropyrans via a One-Pot Organocatalytic Michael/Henry/Ketalization Sequence

27-06-2014 | Robert Hahn; Gerhard Raabe; Dieter Enders, Organic Letters, 2014

A diastereo- and enantioselective Michael/Henry/ketalization sequence to functionalized tetrahydropyrans is described. The multicomponent cascade reaction uses acetylacetone or β-keto esters, β-nitrostyrenes, and alkynyl aldehydes as substrates affording tetrahydropyrans with five contiguous ...

Biomimetic Asymmetric Total Syntheses of Spirooliganones A and B

27-06-2014 | Liyan Song; Hongliang Yao; Rongbiao Tong, Organic Letters, 2014

Biomimetic total syntheses of potent antiviral spirooliganones A and B were achieved with 3% and 2% yield, respectively, in 12 steps from commercially available materials. The synthetic strategy was inspired primarily by the biogenetic hypothesis and was enabled by two independent cascade events: ...

Cyanogramide with a New Spiro[indolinone-pyrroloimidazole] Skeleton from Actinoalloteichus cyanogriseus

26-06-2014 | Peng Fu; Fandong Kong; Xia Li; Yi Wang; Weiming Zhu, Organic Letters, 2014

Cyanogramide (1), an unprecedented alkaloid bearing a novel spirocyclic pyrrolo[1,2-c]imidazole skeleton, was identified from the fermentation broth of the marine-derived Actinoalloteichus cyanogriseus WH1-2216-6. The structure was fully determined by spectroscopic analysis, an exciton chirality ...
