Hetero-Diels–Alder reaction of 1,3-bis(trimethylsilyloxy)-1,3-butadienes with arylsulfonylcyanides. Synthesis and antimicrobial activity of 4-hydroxy-2-(arylsulfonyl)pyridines
摘要:
Hetero-Diels-Alder reactions of 1,3-bis(silyloxy)-1,3-butadienes with arylsulfonylcyanides afforded a variety of 4-hydroxy-2-(arylsulfonyl) pyridines. Several derivatives show antimicrobial activity against Gram-positive bacteria. (c) 2008 Elsevier Ltd. All rights reserved.

2-(Arylsulfonyl)-4-hydroxypyridines were prepared by Hetero-Diels-Alder reaction of 1,3-bis(trimethylsiloxy)buta-1,3-dienes (1,3-bis-silyl enol ethers) with arylsulfonyl cyanides. The products were transformed into 4-aryl-2-(arylsulfonyl)pyridines by Suzuki cross-coupling reactions of the corresponding enol triflates.
