Regioselective coupling reactions of diiodophenol derivatives

Enantiospecific, regioselective cross-coupling reactions of secondary allylic boronic esters.

C-C Coupling Reactions between Benzofurazan Derivatives and 1,3-Diaminobenzenes.

Aromatic substitution reactions between 1,3-diaminobenzene and chloronitrobenzofurazan derivatives have never been reported so far. The aim of the current study was to synthesize novel electron-donor and -acceptor architectures of interest in applied fields and to provide new insights on the nucleophilic behavior of 1,3-diaminobenzenes. The reaction of 1,3-dipiperidinyl-, 1,3-dimorpholinyl-, 1,...

Regioselective ring-opening/cross-metathesis reactions of norbornene derivatives with electron-rich olefins.

This manuscript describes facile ring-opening/cross-metathesis (ROCM) reactions between unsymmetrical norbornene derivatives and electron-rich olefins in the presence of the second-generation Grubbs' catalyst to generate highly substituted furans and pyrroles.

Highly regioselective ring-opening/cross-metathesis reactions of 2-sulfonylnorbornene derivatives.

Tandem ring-opening/cross-metathesis (ROM/CM) reactions of norbornenes can be a powerful entry into highly substituted organic molecules. However, their utility has been limited largely to symmetrical norbornenes because of the general lack of regioselective variants of these reactions. This manuscript describes our successful attempts to address this issue through the use of a sulfone to direc...

Synthesis of Phosphorus Derivatives via Multicomponent Reactions

Stable derivatives of oxaphosphaphenanthrenes were prepared using multicomponent reactions of 3-bromo-2-naphthol, dialkyl acetylenedicarboxylate and trimethyl or triphenyl phosphite under microwave conditions with good yields.
