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. (c) 2005 Elsevier Ltd. All rights reserved.
