Abstract

The syntheses of the C-4 substituted dihydroindoles 25, 31 (scheme 7), and 36 (scheme 8) are described. - The CID MIKE spectrum in the 2. field free region (2. FFR) of m/z 146 from 25 is very similar to but not identical with that of m/z 146 from the C-5 substituted tetrahydroisoquinolines 3,6, 7, and 8 (scheme 2), so supporting our hypothesis of a rearrangement in M+. of ...
