The first part covers the synthesis of hexahydroisoquinolinone derivatives via BF3·OEt2-assisted intramolecular cyclization of alkyl- or aryl-substituted of TBS-protected 2-(ethynyl(tosyl)amino)-methylcyclohex-2-enols and the synthesis of fused-bicyclic δ-lactams via FeCl2-assisted intramolecular cyclization of six-membered yne-ynamide. The second part is the synthesis of pyrrole derivatives via gold(III) chloride-catalyzed intramolecular cyclization of 5-methyl-2-(ethynyl(tosyl)amino)methylfurans. The BF3·OEt2-assisted intramolecular cyclization of alkyl- or aryl-substituted of TBS-protected 2-(ethynyl(tosyl)amino)-methylcyclohex-2-enols enables a straightforward approach to hexahydroisoquinolinone derivatives. Upon epimerization with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), the mixture of diastereomers lead to hexahydroisoquinolinone derivatives as a single isomer. A synthesis of halogenated fused-bicyclic δ-lactams with three stereogenic centers is developed. Treatment of iron(II) chloride with six-membered ring 2-yn-ynamides in THF under dry air afforded halogenated bicyclic δ-lactams in good yields. The reaction are procedurally simple, producing halogenated bicyclic δ-lactams under mild conditions without an additional oxidizing agent. Gold(III) chloride-catalyzed reaction of 5-methyl-2-(enthynyl(tosyl)amino)methylfuran occurred efficiently in toluene at room temperature, leading to a series of pyrrole derivatives The advantages of the reactions are mild reaction conditions、simple experimental operations and high yields.分子內環化反應炔醯胺分子三氟化硼乙醚稠雙環δ -內醯胺六氫異喹啉酮衍生物三氯化金intramolecular cyclizationynamideBF3.OEt2fused-bicyclic δ-lactamhexahydroisoquinolinone derivativesgold(III) chloride
