The first part is the synthesis of pyrroles via 1.2 equiv TMSOTf-promoted tandem reaction of 2-(4-arylpropargylamino- methyl)-3,5,5-trimethyl-2,3-epoxy-cyclohexa-1-ones. The reaction underwent a tandem semi-pinacol rearrangement/alkyne-ketone metathesis to obtain pyrroles. While 1.0 equiv BF3•OEt2 is required for the synthesis of the furans from 2-(4-aryl-propargyloxymethyl)-3,5,5-trimethyl-2,3-epoxy-cyclohexa-1- ones. The second part is the synthesis of azaspirocycles via FeBr3-promoted tandem reaction of 3-(4-arylpropargylaminomethyl)-2,3-epoxy-cyclohexa-1- ones. The reaction underwent a tandem semi-pinacol rearrangement/alkyne– aldehyde metathesis.三氟甲磺酸三甲基矽酯三氟化硼吡咯呋喃螺旋化合物semi-pinacol重排反應炔基–酮基置換反應TMSOTfBF3•OEt2pyrrolefuranazaspirocyclesemi-pinacol rearrangementalkyne-ketone metathesis
