We propose a quantization of the Painlevé system of type A (1) l studied by M. Noumi and Y. Yamada [13]. This quantization has the affine Weyl group symmetry of type A (1) l (l ≥ 2) as well as the Lax representation. For even l, the quantized system of type A (1) l can be obtained as the continuous limit of the discrete system constructed from the affine Weyl group symmetry of type A (1) l+1 .

Repetitive two-step method for o,o,p- and o,p-oligophenylene synthesis through Pd-catalyzed cross-coupling of hydroxyterphenylboronic acid.

A repetitive two-step method involving the Pd-catalyzed Suzuki-Miyaura coupling of hydroxyterphenylboronic acid and the subsequent nonaflation of the hydroxy group has been developed for the synthesis of oligophenylenes. This method readily afforded o,o,p- and o,p-oligophenylenes with defined chain lengths. X-ray crystallography was employed to obtain the structure of the o,p-oligophenylene 9-mer.

Mn(III)-catalyzed radical reactions of 1,3-dicarbonyl compounds and cyclopropanols with vinyl azides for divergent synthesis of azaheterocycles.

Mn(III)-catalyzed formal [3+2]- and [3+3]-annulations have been developed using readily available vinyl azides with 1,3-dicarbonyl compounds and cyclopropanols. Vinyl azides were successfully applied as a three-atom unit including one nitrogen to prepare various azaheterocycles via Mn(III)-catalyzed radical reactions.

N-methyl pyridinium-p-toluene Sulfonate (NMPyTs) catalyzed synthesis of pyrano[2,3-c]pyrazoles

Abstarct:A simple one-pot synthesis of pyrano[ 2,3-c]pyrazoles was developed by a three-component reaction of various benzaldehydes, malononitrile and 1-phenyl or hydro-3-methyl-1H-pyrazol-5(4H)-one in the presence of N-methyl pyridinium p-toluene sulfonate (NMPyTs) as a catalyst. All of the synthesized compounds were identified by IR, 1H NMR, 13C NMR and mass spectroscopy techniques. In the me...
