Synthetic Route of 89830-98-8, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 89830-98-8 as follows.
J-1 a (4.84 g; 44.8 mmol) in TH F (60 mL) was added dropwise to a suspension of NaH (1 .97 g; 49.2 mmol) in TH F (200 mL) at 0¡ãC under N2. The mixture was stirred at RT for 30 min and SEM-CI (9.9 mL; 55.9 mmol) in THF(20 mL) was added dropwise at 0¡ãC. The mixture was stirred at RT under N2 for 16 h. Water was added and the product was extracted with DCM. The organic layer was dried over MgS04, filtered and concentrated under reduced pressure. The crude was purified by preparative LC (Irregular SiOH 20-45 [Jim , 150g Merck, Mobile phase Gradient from 50percent DCM, 50percent heptane to 100percent DCM). The fractions containing pure compound were combined and the solvent was removed under reduced pressure to give 6.6 g of J-1 b as a yellow oil (62percent).Mixture of 2 regioisomers : 70/30Minoritory regioisomer : 1H NMR (DMSO-de, 400MHz) : 5(ppm) 7.64 (s, 1 H), 6.56 (s, 1 H), 5.34 (s, 1 H), 3.45 (t, J = 8.08 Hz, 2H), 1 .73-1 .78 (m, 1 H), 0.80-0.86 (m, 2H), 0.72-0.74 (m, 2H), 0.52-0.57 (m, 2H), -0.04 (s, 9H).Majoritory regioisomer :1H NMR (DMSO-de, 400MHz) : 5(ppm) 7.56 (s, 1 H), 6.94 (s, 1 H), 5.20 (s, 1 H), 3.43 (t, J = 8.08 Hz, 2H), 1 .73-1 .78 (m, 1 H), 0.80-0.86 (m, 2H), 0.72-0.74 (m, 2H), 0.56-0.62 (m, 2H), -0.04 (s, 9H).
According to the analysis of related databases, 89830-98-8, the application of this compound in the production field has become more and more popular.
