... 似物 1b 和 1d 拥有较商品化药物全反式维甲酸(ATRA)更低的 IC 50 值. Abstract The key intermediate boronic acid 2 was synthesized via sequential reactions of Friedel-Crafts alkylation, bromination and nucleophilic reaction by using anisole as starting material. Hydroxyacetone was converted to bromide compound 3 by the Wittig reaction, bromination, Arbuzov reaction and Horner-Wadsworth-Emmons (HWE) reaction. Three novel retinoid derivatives 1a~1c can be obtained via the Suzuki coupling reaction of the boronic acid 2 with bromide compound 3, methyl 4-bromo-2-fluorobenzoate (4) or methyl 6-bromonicotinate (5) and followed by hydrolysis of the corresponding esters. In addition, trifluoromethyl substituted retinoid derivative 1d was synthesized via sequential reactions of Friedel-Crafts alkylation, nitration, trifluoromethylation, reduction and nucleophilic reaction with bromobenzene as strarting material. The structures of four new retinoid derivatives 1a~1d were confirmed by 1 H NMR, 13 C NMR, IR and HRMS analyses. Furthermore, the inducing differentiation abilities of molecules 1a~1d for HL-60 cells were tested, and the results revealed that these four retinoid derivatives are biological active. The IC 50 values of fluorinated derivatives 1b and 1d are lower than that of commercial medicine all trans retinoid acid (ATRA).
