Synthesis of the tetracyclic core of daphnilactone B-type and yuzurimine-type alkaloid [PDF]

, 2011
: The core of daphnilactone B-type and yuzurimine-type alkaloids was synthesized in only 16 steps from a known β-allyl-γ-butyrolactone. The key sequence of Vilsmeier–Haack cyclization and intramolecular azomethine ylide cycloaddition allowed the ...

Photooxygenation of Non-Aromatic Heterocycles [PDF]

, 2007
Photooxygenation of non-aromatic heterocycles and cyclic compounds containing non-usual heteroatoms, namely silicon, germanium and tellurium has been reviewed. All three types of photooxygenation (Types I-III) can take place.

Multicomponent synthesis, biological evaluation and molecular docking of new spiro-oxindole derivatives

Journal of Taibah University for Science, 2017
A new series of spiro-oxindoles that were identified based upon their ability to inhibit methionine tRNA synthase (PDB ID: 1PFV) and glucosamine-6-phosphate synthase (PDB ID: 1JXA) enzymes in virtual screening was synthesized by a three-component 1,3 ...
