Facile synthesis of benzoxazoles from 1,1-dibromoethenes

Autor: Kemei Tao, Zhaogui Liu, Jiancun Zhang, Jianlong Zheng, Wang Shen

Publikováno v: Tetrahedron Letters. 51:3246-3249

Direct coupling of 1,1-dibromoethenes with 2-aminophenols had been achieved to form the corresponding benzoxazoles under mildly basic reaction conditions. A variety of substituted 2-aminophenols provided the desired products in moderate to good yield

N,N′-Di-Boc-Substituted Thiourea as a Novel and Mild Thioacylating Agent Applicable for the Synthesis of Thiocarbonyl Compounds

Autor: Biaolin Yin, Zheng-Rong Li, Jiancun Zhang, Zhaogui Liu

Publikováno v: Synthesis. 2010:991-999

Stable and readily available N,N'-di-Boc-substituted thiourea, when activated with trifluoroacetic acid anhydride, was used as a novel thioacylating agent. Through the thioacylation of nucleophiles, such as amines, alcohols, thiols, sodium benzenethi

Highly stereoselective synthesis of 2′-deoxy-β-ribonucleosides via a 3′-(N-acetyl)-glycyl-directing group

Autor: Biaolin Yin, Jiancun Zhang, Deyao Li, Zhaogui Liu

Publikováno v: Tetrahedron Letters. 51:240-243

A facile synthesis of 2′-deoxy-β-ribonucleosides from 3′-O-(N-acetyl)-glycyl-protected 2′-deoxyribofuranose has been developed. The coupling reactions between the protected 2′-deoxyribose and silylated bases exhibited β-selectivity up to 98

Efficient and selective cleavage of the t-butoxycarbonyl group from di-t-butylimidodicarbonate using catalytic bismuth(III) bromide in acetonitrile

Autor: Biaolin Yin, Sheng Jiang, Wenming Huang, Xiaopeng Li, Jianlong Zheng, Zhaogui Liu, Hequan Yao, Jiancun Zhang

Publikováno v: Tetrahedron Letters. 50:5094-5097

Di-t-butylimidodicarbonates can be chemoselectively and efficiently deprotected to the corresponding mono-BOC-protected amines in high yields using a catalytic amount of bismuth(III) bromide in acetonitrile at room temperature. This method is mild an
