Article abstract of DOI:10.1039/p19960002005

The addition of thionyl chloride to dihydroisoquinolines affords isoquinolinium chlorides which are readily converted to the corresponding ylides upon treatment with sodium hydrogen carbonate. These ylides undergo facile 1,3-dipolar additions with dimethy
