Synthesis of 7,8-benzo-9-aza-4-oxabicyclo[3.3.1]nonan-3-ones by sequential 'condensation-iodolactonization' reactions of 1,1-bis(trimethylsilyloxy)ketene acetals with isoquinolines

Functionalized 7,8-benzo-9-aza-4-oxabicyclo[3.3.1]nonan-3-ones were prepared by regio- and diastereoselective condensation of 1,1-bis(silyloxy) ketene acetals with isoquinolinium salts and subsequent regioselective and stereospecific iodolactonization.

Reactions of Trialkylsilyl Trifluoromethanesulfonates, VI. - Synthesis of 2-Heterosubstituted O-Alkyl-O-(trimethylsilyl)ketene Acetals and 2-(Trimethylsilyl)carboxylates

Organooxy- and (alkylthio)ethanoic acid esters 2 are silylated by trimethylsilyl triflate (1) in the presence of triethylamine to yield mixtures of ketene acetals 3 and 2-(trimethylsilyl)ethanoates 4.The product distributions 3/4 are governed by the ester groups and the substituents in α position.Cyclic derivatives of 2-hydroxycarboxylic acids 7,9 are silylated by 1/triethylamine to give the ketene acetals 8,10.From N-protected glycine methyl esters 11,12 the ketene acetals 13,15 are obtained in the reaction with 1/triethylamine.
