Tandem reactions of cis-2-acyl-1-alkynyl-1-aryl cyclopropanes tuned by gold(i) and silver(i) catalysts: efficient synthesis of pyran-fused indene cores and 2,4,6-trisubstituted phenols
Tandem reactions of cis-2-acyl-1-alkynyl-1-aryl cyclopropanes tuned by gold(i) and silver(i) catalysts: efficient synthesis of pyran-fused indene cores and 2,4,6-trisubstituted phenols
Tandem reactions of cis-2-acyl-1-alkynyl-1-aryl cyclopropanes 1 tuned by gold(I) and silver(I) catalysts are described, which afford selectively the key pyran-fused indene cores 2 and the 2,4,6-trisubstituted phenols 3 in good yields, respectively.
