Silane-mediated direct condensation of nitroarenes with cinnamyl-type sulfones. The way to 2-aryl-4-X-quinolines and their hetero analogs
摘要:
DBU/silane mediated double condensation of nitroarenes with cinnamyl-type sulfones proceeds smoothly to yield 2-aryl-4-arylsulfonyl quinolines and their hetero analogs. Arylsulfonyl group can be easily replaced by different nucleophiles. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
