  Syntheses, separation of enantiomers and barriers to racemization of some sterically hindered N-aryl-1,2,3,4-tetrahydro-3,3-dimethyl-2,4-quinolinediones and their thio analogues

  摘要：

  The novel N-aryl-1,2,3,4-tetrahydro-3,3-dimethyl-2,4-quinolinediones 1, 4 and 8 were thiated with Lawesson reagent and P4S10 to yield the monothio derivatives 2 and 5 and the dithio compounds 3, 6 and 9. Their enantiomers were separated by liquid chromatography on triacetyl- or tribenzoylcellulose. Rotation barriers for 1-4 and 8 were determined by thermal racemization and discussed in terms of steric effects.
