Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 1427311-76-9, name is (S)-1-(4-Iodo-5-methoxy-2-nitrophenyl)-2,2-dimethylpropan-1-ol, A new synthetic method of this compound is introduced below., Recommanded Product: (S)-1-(4-Iodo-5-methoxy-2-nitrophenyl)-2,2-dimethylpropan-1-ol
Compound 38 (350 mg, 0.54 mmol) and (5)-l-(4-iodo-5-methoxy-2-nitrophenyl)-2,2- dimethyl- 1 -propanol (720 mg, 1.97 mmol) were heated at 110C for 45 min under a nitrogen atmosphere. The mixture was cooled down to room temperature, dissolved in MeOH (10 mL), and followed by addition of NH4F (400 mg, 11.1 mmol). The mixture was stirred at 50 C for 12 hours, concentrated in vacuo, dissolved in CH2CI2 (50 mL), and washed with brine (50 mL). The organic phase was dried over Na2S04, concentrated in vacuo, and the residue was purified by silica gel chromatography to yield 5-[(5)-l-(4-iodo-5-methoxy-2- nitrophenyl)-2,2-dimethyl-propyloxy]methyl-2′-deoxyuridine 61 (90 mg, 28%). 1HNMR (400 MHz, CDCl3): delta 8.34 (s, 1 H, Ph-H), 7.65 (s, 1 H, H-6), 7.12 (s, 1 H, Ph-H), 6.17 (t, 1 H, J = 6.8 Hz, Eta-Gamma), 5.18 (s, 1 H, Ph-CH), 4.59 (m, 1 H, H-3 ‘), 4.27 (d, 1 H, J = 12.0 Hz, 5-CH2a), 4.15 (d, 1 H, J = 12.0 Hz, 5-CH2b), 4.00 (m, 1 H, H-4’), 3.97 (s, 3 H, OCH3), 3.95 (m, 1 H, H-5’a), 3.82 (m, 1 H, H-5’b), 2.34 (m, 2 H, H-2), 0.84 (s, 9 H, C(CH3)3).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
