Abstract

Complete stereocontrol with the added advantage of functional-group tolerance in copper-catalyzed 1,4-additions of organozinc reagents to enones has been achieved for the first time with the chiral phosphoramidite L* as ligand in the copper complex [Eq. (a), Tf = trifluoromethanesulfonate]. The zinc enolate intermediate of the reaction can be trapped with aldehydes.

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.
