Adding a certain compound to certain chemical reactions, such as: 1113-21-9, 3,7,11,15-Tetramethylhexadeca-1,6,10,14-tetraen-3-ol, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Recommanded Product: 3,7,11,15-Tetramethylhexadeca-1,6,10,14-tetraen-3-ol, blongs to alcohols-buliding-blocks compound. Recommanded Product: 3,7,11,15-Tetramethylhexadeca-1,6,10,14-tetraen-3-ol
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).
The synthetic route of 1113-21-9 has been constantly updated, and we look forward to future research findings.
