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 597-31-9, name is 3-Hydroxy-2,2-dimethylpropanal. This compound has unique chemical properties. The synthetic route is as follows. HPLC of Formula: C5H10O2
Example 214 3-(((3R,3aS,9bS)-9b-((4-fluorophenyl)sulfonyl)-7-(perfluoropropan-2-yl)-2,3,3a,4,5,9b-hexahydro-1H-cyclopenta[a]naphthalen-3-yl)amino)-2,2-dimethylpropan-1-ol A solution of (3R,3aS,9bS)-9b-((4-fluorophenyl)sulfonyl)-7-(perfluoropropan-2-yl)-2,3,3a,4,5,9b-hexahydro-1H-cyclopenta[a]naphthalen-3-amine (Example 114; 20.0 mg, 0.039 mmol) in DCM (1 mL) was treated with DIEA (14 muL, 0.078 mmol) and 3-hydroxy-2,2-dimethylpropanal (39.8 mg, 0.390 mmol) and stirred at rt. After 45 min the mixture was treated with sodium triacetoxyborohydride (33.0 mg, 0.156 mmol) and stirred at rt overnight. The mixture was treated with a drop of saturated aqueous NaHCO3, concentrated and purified by preparative HPLC (Method E, gradient 48-88% B, 20 min) to provide 3-(((3R,3aS,9bS)-9b-((4-fluorophenyl)sulfonyl)-7-(perfluoropropan-2-yl)-2,3,3a,4,5,9b-hexahydro-1H-cyclopenta[a]naphthalen-3-yl)amino)-2,2-dimethylpropan-1-ol (7.2 mg, 30% yield). LCMS m/z 600.2 (M+H)+; HPLC tR 1.91 min (Method C). 1H NMR (500 MHz, DMSO-d6) delta 7.48 (s, 2H), 7.36-7.20 (m, 5H), 3.25-3.14 (m, 2H), 2.98 (br dd, J=10.8, 3.5 Hz, 1H), 2.82 (q, J=7.2 Hz, 1H), 2.73-2.66 (m, 1H), 2.61 (br d, J=15.6 Hz, 1H), 2.48-2.32 (m, 2H), 2.22-2.06 (m, 2H), 2.03-1.82 (m, 3H), 1.75-1.60 (m, 1H), 1.35-1.17 (m, 1H), 0.82 (2s, 6H).
With the rapid development of chemical substances, we look forward to future research findings about 597-31-9.
