摘要

An efficient and versatile tandem process of acetalization and cycloiso-merization reactions has been developed for the reactions of l-alkynyl-2-carbonyl-quinoline substrates.The reaction occurs thanks to Au~I and Ag~I catalysis.Silver(I)catalysis has been extensively studied(11 different silver species)on a broad range of quinoline derivatives(variation of alkyne substituent,of carbonyl function and of nucleophiles),leading to a variety of furoquinoline and pyranoquinoline moieties.An insight is given for the presumed mechanism along with DFT-B3LYP/6-31G** calculations to address the 6-endo and 5-exo regioselectivities observed.
