Synthetic Route of 1113-21-9, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 1113-21-9, name is 3,7,11,15-Tetramethylhexadeca-1,6,10,14-tetraen-3-ol. This compound has unique chemical properties. The synthetic route is as follows.
Example 5: 5E,9E,13E-Geranylgeranyl Acetone Synthesis[0141] Alternative synthesis of 5-trans Isomer: 5E,9E,13E-Geranylgeranyl acetone 1: The alternative synthesis of 5E,9E,13E-geranylgeranyl acetone 1 can be achieved as shown in the scheme-5.Scheme 5:[0142] The 5E, 9E, 13E-geranyl geranyl acetone (1) can be prepared by reacting 6E-10E- geranyl linalool (23) with diketene (24) catalyzed by DMAP in ethyl ether to give the ester 25. The ester 25 in the Carroll rearrangement using Al(OiPr)3 at elevated temperature can afford the desired 5E, 9E, 13E-geranyl geranyl acetone (1). In another approach, the GGA (1) can be prepared by treating geranyl linalool (23) with the Meldrum’s acid 26 in the Carroll rearrangement using Al(OiPr)3 at 160 C. Similarly, the use of tert-butyl acetoacetate (27) with geranyl linalool (23) in the Carroll rearrangement can also give the desired 5E, 9E, 13E-geranyl geranyl acetone (1).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 1113-21-9, 3,7,11,15-Tetramethylhexadeca-1,6,10,14-tetraen-3-ol.
