Closed access Metadata (CSL-JSON)
DOI 10.1055/s-0039-1690889
Data confidence 70 medium
How this score is calculated

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

Organophosphorus pyrrolidine derivatives possessing P–N bonds are a promising yet underexplored class of compounds. In this short review we overview the general approaches to these compounds described so far, with a special emphasis on their asymmetric synthesis. 1 Introduction 2 Synthesis of Pyrrolidine-Based P(III) Derivatives 3 Synthesis of Pyrrolidine-Based P(V) Derivatives 3.1 Phosphorylation of Pyrrolidines with P(V) Acid Chlorides 3.2 Phosphorylation of Pyrrolidines with P(V) Acid Esters 3.3 Syntheses via the Atherton–Todd Reaction 3.4 Oxidation of Pyrrolidine-Based P(III) Derivatives 4 Syntheses of N-Phosphorylpyrrolidines from Acyclic Precursors 5 Conclusions
