Modern Methods for Conjugated Polymers Preparation: A Concept of Transition Metal‐Free Synthesis
Conjugated polymers (CPs) are promising organic materials currently at the center of the organic electronics revolution. Synthesis strategies play a crucial role in the rise of this field, and this review aims to shed light on transition metal‐free organic chemistry for the synthesis of conjugated polymers, which is currently experiencing a renaissance.

Application of 1,3-Dipolar Reactions between Azomethine Ylides and Alkenes to the Synthesis of Catalysts and Biologically Active Compounds [PDF]
The (3+2) cycloaddition between azomethine ylides and alkenes is an efficient, convergent and stereocontrolled method for the synthesis of unnatural pyrrolidine and proline scaffolds.

A convenient synthesis of planar chiral [2.2]paracyclophane imidazoline N,O‐ligands has been developed. The application of these classes of ligands showed excellent performance in organozinc additions to aldehydes. An improved seven‐step synthesis of [2.2]paracyclophane‐imidazoline N,O‐ligands (UCD‐Imphanols) possessing both central and planar ...

New Chemistry of Imidazolinium ylides [PDF]
Previous work in this group has shown 4,5-dihydroimidazolium ylides, formed by N- alkylation of 4,5-dihydroimidazoles, to undergo 1,3-dipolar cycloadditions with a range of dipolarophiles in a highly regio- and stereoselective fashion.

Total Synthesis of (−)-Daphenylline [PDF]
Total synthesis of (−)-daphenylline, a hexacyclic Daphniphyllum alkaloid, was achieved. Construction of the tricyclic DEF ring system was initiated by asymmetric Negishi coupling followed by an intramolecular Friedel–Crafts reaction.

One pot synthesis of pyrrolidines type 3,7-diazabicyclo [3.3.0] octane and biological activity [PDF]
Pyrrolidines type 2,4-disubstituted (alkyl, aryl or heteroaryl)-6,8-dioxo-3,7-diazabicyclo [3.3.0] octanes (8a-d) were successfully synthesized by an efficient one pot 1,3-dipolar cycloaddition of azomethine ylides (in situ generated from the reaction of

Highly diastereoselective synthesis of substituted pyrrolidines using a sequence of azomethine ylide cycloaddition and nucleophilic cyclization [PDF]
: Although cycloadditions of azomethine ylides usually give mixtures of endo/exo adducts, we successfully tuned the mechanistic path of a new reaction cascade to afford substituted pyrrolidines in high yields and diastereomeric purity.

Strecker degradation of amino acids promoted by a camphor-derived sulfonamide [PDF]
A camphor-derived sulfonimine with a conjugated carbonyl group, oxoimine 1 (O2SNC10H13O), reacts with amino acids (glycine, L-alanine, L-phenylalanine, L-leucine) to form a compound O2SNC10H13NC10H14NSO2 (2) which was characterized by spectroscopic means
