Abstract:
2,6,10-TRIMETHYLDODECA-2,6,11-TRIEN-10-OL-1-AL (I) and its acetals and a process for the production of these important precursors of sinensal via the new acetals of 2,6-dimethyl-2,6undecadien-10-on-1-al (V). (I) is obtained from acetals of 2methyl-6-oxo-hept-2-en-1-al by vinylation or ethynylation followed by partial hydrogenation; reaction of the new allyl alcohols obtained with diketene or an acetoacetic ester to form the new acetals (V); vinylation or ethynylation followed by partial hydrogenation of the new acetals (V) and acid hydrolysis.
