Targeting Structural and Stereochemical Complexity by Organocascade Catalysis: Construction of Spirocyclic Oxindoles Having Multiple Stereocenters
Abstract
Nicht so schwierig, wie es aussieht: Der asymmetrische Aufbau komplexer Oxindol-Spirocyclen mit mehreren Stereozentren gelang durch Reaktionskaskaden mit zwei Organokatalysatoren, die jeweils unterschiedliche Carbonylverbindungen aktivieren (siehe Schema; TMS=Trimethylsilyl). Die sich ergänzenden Ansätze belegen das Potenzial organokatalytischer Kaskaden für knifflige Syntheseprobleme.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
