  4‐(alkyl or arylsulfonamido)‐2‐naphthoates from ethyl (E)‐α‐ethynyl‐β‐aryl‐α,β‐unsaturated esters (1) and N‐sulfonyl azides (2) in the presence of 2,6‐lutidine in THF at 60 °C for 3 h was developed in one step, in which a copper(I)‐catalyzed 1,3‐dipolar cycloaddition, ketenimine formation, and 6π‐electrocyclization followed by [1,3]‐H shift tandem reaction took place. This method enabled efficient synthesis

  The regio- and chemoselective synthetic method of functionalized alpha-hydroxyalkyl allenic esters was developed from the reactions of various aldehydes with organoindium reagent generated in situ from indium and ethyl 4-bromobutynoate. The alpha-hydroxyalkyl allenic esters possessing electron-donating groups were cyclized to ethyl 2-naphthoate derivatives through intramolecular C-alkylation catalyzed by gold salts.

  Treatment of a wide range of functionalized hydroxyallenic esters with 5 mol % Ph3PAuCl and 5 mol % AgOTf in CH2Cl2 at 25 degrees C for l h produced selectively 2-alkyl- and aryl-3-ethoxycarbony1-2,5-dihydrofurans in good to excellent yield through intramolecular hydroalkoxylation by a 5-endo mode.

  Ethyl alpha-(1-hydroxy-1-alkyl)methylallenoates and alpha-(1-hydroxy-1-aryl)methylallenoates containing not only electron-donating groups but also an electron-withdrawing group on the aryl group at the alpha-position have been shown to undergo an efficient and selective copper-catalyzed intramolecular hydroalkoxylation to give functionalized 3-ethoxycarbony1-2-alkyl- and -aryl-2,5-dihydrofurans in good to excellent yields through a 5-endo mode.
