The first part is the synthesis of bridged bicyclic δ-lactams via gold(I)-catalyzed intramolecular cycloisomerization/ox -idation of N-tosyl-4-ynamidomethylcyclohexenes. The second part is the synthesis of hexahydroisoquinolinone derivatives via BF3.OEt2-promoted intramolecular cyclization of alkyl- or aryl-substituted O-silyl-protected 2-((ethynylamino)methyl)cyclohex-2-enols. N-Tosyl-4-ynamidomethylcyclohexenes underwent cycloisomerization in the presence of a catalytic amount of a gold(I) complex delivering 4-azatricyclo[4.2.2.03,8]dec-2-ene derivatives as the major products under mild reaction conditions with high diastereoselectivities. Upon oxidation with osmium tetraoxide and N-methylmorpholine-N-oxide, alkyl- or aryl-substituted azatricycles led to bridged bicyclic δ-lactams. Under acidic conditions, the alkyl-substituted azatricycles were further transformed into 4-N-tosylaminomethyl-tethered bicyclo[4.2.0]octan-7-ones derivatives. The BF3.OEt2-promoted intramolecular cyclization of alkyl- or aryl-substituted O-silyl-protected 2-((ethynylamino)methyl)cyclohex-2-enol enables a straightforward approach to hexahydroisoquinolinone derivatives. Upon epimerization with 1,8-diazabicyclo[5.4.0]undec-7-ene, the mixture of diastereomers afforded hexahydroquinolinone derivatives as a single isomer.分子內環化反應炔醯胺分子金催化橋雙環δ-內醯胺三氟化硼乙醚六氫異喹啉酮衍生物intramolecular cyclizationynamidegold(I)-catalyzedbridged bicyclic δ-lactamBoron trifluoride diethyl etheratehexahydroisoquinolinone derivatives
