Nine novel (+)-camphor-derived thioureas have been prepared. 3-((Dimethylamino)methylene)camphor (2) served as the common precursor for the preparation of both, 2-thiourea 15-20 and 3-thiourea functionalized camphor derivatives 6, 7/7′, respectively. Starting from 2, the latter were prepared in two or three steps whereas the former in five steps, respectively. Configuration of all novel compounds has been meticulously determined using NMR techniques and/or single crystal X-ray crystallography. Copyright

The exo and endo α-benzyl derivatives (1 and 2. respectively) of (+)-camphor have been synthesized and are found to exert a strong influence on the circular dichroism n?* Cotton effects: 1: Δε301max -0.36 (n-heptane) and 2: Δε302max +3.22, relative to camphor: Δε304max + 1.8 (n-heptane).Evidence for electric dipole transition moment coupling in these γ,δ-unsaturated systems is found in the n?* UV: 1: ε291max 84 (n-heptane) and 2: ε285max 303, relative to camphor: ε290max 25.
