Stereoselective, Ag-Catalyzed Cyclizations to Access Polysubstituted Pyran Ring Systems: Synthesis of C1-C12 Subunit of Madeirolide A
The exploration into the scope of a silver-catalyzed cyclization (AgCC) of propargyl benzoates for accessing pyran ring systems has been reported. The impact of the degree of substitution, nature of the substitution on the carbon backbone/benzoate moiety,
