Effect of Overcrowding in [n]Radialenes on the Synthesis of Bis[4]radialenes

Autor: Toshihiro Watanabe, Shunji Hyoda, Mark Botoshansky, Menahem Kaftory, Fumio Toda

Publikováno v: The Journal of Organic Chemistry. 64:2287-2292

The crystallization of CuCl-assisted dimerization of 2-bromo-3,4-bis(diphenylmethylene)cyclobutanone revealed two polymorphs (3 and 4). The dimer was intended to be a precursor to bis-radialenes. Attempts to dehydrogenate the compound to the true bis

Efficient resolution of 2,2′-dihydroxy-1,1′-binaphthyl by inclusion complexation with chiral N-(3-chloro-2-hydroxypropyl)-N,N,N-trimethylammonium chloride

Autor: Irene M. Mavridis, Shinji Toyota, Spyros D. Chatziefthimiou, Kazuhiro Yoshizawa, Fumio Toda, Shunji Hyoda

Publikováno v: Org. Biomol. Chem.. 2:449-451

The complete resolution of 2,2[prime or minute]-dihydroxy-1,1[prime or minute]-binaphthyl into its enantiomers by inclusion complexation with a commercially available derivative of choline, is reported. The two enantiomers are recovered in99% ee from

Method of Producing Choline of a High Purity

Autor: Youichi Hasegawa, Shunji Hyoda, Fumio Toda

Publikováno v: Novel Trends in Electroorganic Synthesis ISBN: 9784431659266

A method of producing a choline having a high purity without containing by-products by using a molecule-inclusion complex of the choline as a starting material. A choline inclusion complex without containing by-products is obtained by reacting an aqu

Isolation of anhydrous hydrazine as stable inclusion complexes with hydroquinone and p-methoxyphenol, and their solid state reaction with esters which gives pure hydrazides

Autor: Shunji Hyoda, Fumio Toda, Kengo Okada, Ken Hirotsu

Publikováno v: Journal of the Chemical Society, Chemical Communications. :1531

Anhydrous hydrazine is isolated in a pure state as a stable inclusion complex crystal with hydroquinone or p-methoxyphenol, the X-ray structures of which have been analysed; the solid-state reaction of the hydrazine inclusion complex and esters gives
