It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
Abstract A first successful synthesis of 2‐(het)aryl‐N‐phosphorylpyrrolidines is reported starting from readily available N‐(4,4‐diethoxybutyl)amides of P(V) acids. A range of phenols and hydroxyl‐substituted O‐heterocycles may be employed into the reaction furnishing N‐phosphorylated 2‐(het)arylpyrrolidines with up to 90 % yield. The developed method permits a presence of sensitive to phosphorylation hydroxy groups and provides the easy and regioselective entry to target compounds.
