Abstract

Convenient One-Pot Synthesis of 4,8-Dimethyl-bicyclo(3.3.1)non-7en-2-ol via Platinum/Tin Catalyzed Hydroformylation/Cyclization of Limonene.-Under optimized conditions limonene (I) is transformed in a one-step process to the alcohol (III), which is a useful compound in the perfumery industry. Together with the desired compound 11% of hydrogenated and 4% of isomerized material is found. In the absence of Sn-or Pt-complexes no hydroformylation is observed. -(DE O.
