The mixture was sparged with argon for 10 min and then sealed in a pressure vial which was warmed to 82[deg.] C. and held for 40 h. The crude reaction mixture was partitioned between CH2Cl2 and 0.1 M HCl solution. The organic layer was washed with 0.1 M HCl (2*), brine (2*), and saturated aqueous NaHCO3 (2*), dried over MgSO4 and concentrated under reduced pressure. The dark yellow oil was purified by column chromatography on silica gel (25% hexanes in Et2O) to give 0.700 g (51%) of the title compound as primarily the Z isomer.

86% In methanol; acetonitrile; at 20℃; for 24h; To a solution of (S,S)-(+)-1,2-diaminocyclohexane (0.38 g, 3.3 mmol) in CH3CN (160 ml) was added a solution of 2,6-diformyl-4-bromophenol (0.69 g, 3.0 mmol) in MeOH (60 ml). The mixture was stirred at room temperature for 24 h. The Schiff-base macrocycle separated as a yellow solid, was filtered, and recrystallized from CH2Cl2-CH3CN.

YieldReaction ConditionsOperation in experiment
92% With sodium methylate; acetic acid at 90℃; for 0.333333h; Microwave irradiation; Synthesis of 17a-f: General procedure: To a 5 mL glass tube, sodium methoxide (1 mmol) was added to the mixture of 2,6-diformylphenols 15a-c (0.5 mmol) and rhodanines 9a,c (1.1 mmol) in acetic acid (2 mL). The reaction tube was placed inside the cavity of the microwave, operated at power 200-250 W. The tube was irradiated in the microwave oven for appropriate time and temperature (according to Table 3). The work-up and purification step was the same used for conventional thermal heating.

After TLC monitored the reaction of the raw material N2, the temperature was lowered to room temperature. DCM (500ml) was rinsed, and the organic phase was dried and spin-dried to obtain a crude product. The crude product was purified by column purification (petroleum ether: ethyl acetate = 5: 1) to obtain pure A (107g), purity: 98.8%, yield 70%.
