Palladium-Catalyzed Amination of Unprotected Five-Membered Heterocyclic Bromides

Organic Letters (2014)

Mingjuan Su Naoyuki Hoshiya Stephen L. Buchwald

An efficient method for the palladium-catalyzed amination of unprotected bromoimidazoles and bromopyrazoles is presented. The transformation is facilitated by the use of our newly developed Pd precatalyst based on the bulky biarylphosphine ligand tBuBrettPhos (L4). The mild reaction conditions employed allow for the preparation of a broad scope of aminoimidazoles and aminopyrazoles in moderate to excellent yields.

Synthesis and Cytotoxic Activity of N,N′-(Arylmethylene)bisamides

Synthesis (2015)

Jun’ichi Uenishi Tatsuhiro Yoshiki Hirokazu Hirano Tsuyoshi Ueda Naoyuki Hoshiya

N,N′-(Arylmethylene)bisamides were prepared by an acid-catalyzed reaction of arylaldehydes with cinnamamide or acrylamides. The reaction was carried out in refluxing toluene for a few hours, and simple collection of the precipitate gave the desired products. The bisamides were designed as cytotoxic molecules based on the structure of the potently cytotoxic marine natural product (–)-zampanolide. The activities of the bisamides against two cancer cell lines were evaluated, and several compounds were found to show medium potency with IC₅₀ values in the lower micromolar level.

Ligand‐Free Buchwald–Hartwig Aromatic Aminations of Aryl Halides Catalyzed by Low‐Leaching and Highly Recyclable Sulfur‐Modified Gold‐Supported Palladium Material

Advanced Synthesis & Catalysis (2012)

Mohammad Al‐Amin Tetsuo Honma Naoyuki Hoshiya Satoshi Shuto Mitsuhiro Arisawa

Abstract A stable heterogeneous catalyst precursor, sulfur‐modified gold‐supported palladium material (SAPd), has proved to be an excellent source of leached, ligand‐free, Pd for the amination of aryl bromides and chlorides. The reaction‐enabling catalyst is provided in situ as leached Pd in low catalyst loading (0.21±0.02 mol%). This allows the precatalyst (SAPd) to be filtered off and used for a minimum of ten reaction cycles without loss of catalytic activity. SAPd released only trace amounts, less than 0.6 ppm, of highly active Pd during the reaction without any aggregation.
