The synthesis of 3-amino-5-arylisothiazoles from propynenitriles
摘要:
A new synthesis of 3-amino-5-arylisothiazoles is reported. The reaction is operationally simple, utilises readily synthesised propynenitriles as starting materials and is tolerant of a range of functional groups. The optimised reaction conditions can also be used with 3-chloropropenenitriles in place of propynenitriles. (C) 2018 Elsevier Ltd. All rights reserved.

Cyanoalkynes were synthesized in fair to good yields from terminalacetylenes and cuprous cyanide in the presence of trimethylsilyl chloride, water, catalytic amount of sodium iodide, and CH3CN in DMSO at 50°C.
Synthesis of (Z)-3-aryloxy-acrylonitriles, (E)-3-aryloxy-acrylonitriles and 3-cyanobenzofurans through the sequential reactions of phenols with propiolonitriles

日期:——
A Na2CO3-promoted addition of phenols to propiolonitriles generated (Z)-3-aryloxy-acrylonitriles in nearly quantitative yields with exclusively Z-isomers, and a DABCO-promoted addition reaction of phenols with propiolonitriles afforded mainly (E)-3-aryloxy-acrylonitriles with high yields. The obtained (E)-3-aryloxy-acrylonitriles underwent intramolecular cyclization to give 3-cyanobenzofurans in good yields through palladium-catalyzed direct C–H bond functionalization.

A concise copper(I)‐catalyzed oxidativetransformation of aryl propargyl azides to arylpropiolonitriles has been developed. Arylpropiolonitrile derivatives can be obtained in moderate to good yields by this strategy. An oxidative Schmidt rearrangement is involved in this transformation.
