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

Asymmetric phosphine catalysis showcasing remarkable progress over the past two
decades has emerged as a key synthetic platform for the creation of molecular frameworks …

The enantioselective synthesis of spirocycles has long been pursued by organic chemists.
Despite their unique 3D properties and presence in several natural products, the difficulty in …

A library of novel bis-Schiff base derivatives based on thiobarbituric acid has been
effectively synthesized by multi-step reactions as part of our ongoing pursuit of novel anti …

The principle of vinylogy states that the electronic effects of a functional group in a molecule
are possibly transmitted to a distal position through interposed conjugated multiple bonds …

The first highly enantioselective phosphine‐catalyzed formal [4+ 4] annulation has been
developed. In the presence of amino‐acid‐derived phosphines, the unprecedented [4+ 4] …

Well‐developed asymmetric organocatalysis has been widely incorporated in various
cascade/tandem sequences, providing a simple access to structurally complex target …

Catalytic addition of chiral phosphine, that is,(R)‐or (S)‐SITCP, to an α‐substituted allene
ester generated a zwitterionic dipole. Under optimized reaction conditions, this dipole could …

A phosphine-catalyzed highly enantioselective [4+ 2] annulation between ortho-quinone
methides and allene ketones has been developed. The reported method led to the formation …

A palladium-catalyzed enantioselective [4+ 2] cycloaddition reaction of vinyl
benzoxazinones with sulfamate-derived cyclic imines is described, affording the …
