The hallmark of nucleophilic phosphine catalysis is the initial nucleophilic addition of a
phosphine to an electrophilic starting material, producing a reactive zwitterionic intermediate, …

Ethyl 2-methyl-2,3-butadienoate acts as a 1,4-dipole synthon and undergoes [4 + 2]
annulation with N-tosylimines in the presence of an organic phosphine catalyst. The resulting …

Phosphine-catalyzed [4 + 2] annulations of α-alkylallenoates with activated olefins allow the
efficient syntheses of cyclohexenes. Hexamethylphosphorous triamide (HMPT)-catalyzed [4 …

Phosphorus-based organocatalysis encompasses several subfields that have undergone
rapid growth in recent years. This Outlook gives an overview of its various aspects. In particular…

Nucleophilic phosphine catalysis of allenes with electrophiles is one of the most powerful
and straightforward synthetic strategies for the generation of highly functionalized carbocycle …

We have prepared two new diastereoisomeric 2-aza-5-phosphabicyclo[2.2.1]heptanes from
naturally occurring trans-4-hydroxy-l-proline in six chemical operations. These syntheses …

In this paper we describe the phosphine-catalyzed [3 + 2], [3 + 3], [4 + 3], and [3 + 2 + 3]
annulations of azomethine imines and allenoates. These processes mark the first use of …

This review discusses the tertiary phosphines possessing various chiral skeletons that have
been used in asymmetric nucleophilic organocatalytic reactions, including annulations of …

Bisphosphine-catalyzed mixed double-Michael reactions have been developed to afford β-amino
carbonyl derivatives of oxazolidines, thiozolidines, and pyrrolidines in excellent yields …
