The latter, which has a wide range of industrial applications, was used to enantioselectively synthesize the (5R,6S)-5 Hydroxymethyl-6-methylbicyclo[2.2.1] hept-2-ene norbornene derivative (Fig. ) using the Oppolzer Camphorsultam intermediate as a chiral auxilary (1S,5R,7R)-10,10-Dimethyl-3thia-4-azatricyclo[5.2.1.0]decane 3,3-dioxide. Norbornene does not have a wide range of practical of applications. However, this molecule is mainly used to produce intermediates for pharmaceutical compounds, pesticides and some special perfumes . In organic chemistry, it is used in the synthesis of iridoids (Fig. ) which represent a class of oxygenated monoterpenes present in many medicinal plants, giving them therapeutical properties (cardiovascular, analgesic, anti-inflammatory). Hence its of a considerable interest in organic synthesis. . Herein, we highlight the total chiral lewis acid catalyzed (titanium complexes) synthesis of molecule (1) by following simple steps using as few toxic reagents as possible.
