TLC (ten methanol PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/21034305 in chloroform, Rf = 0.three) confirmed the completion on the reaction by disappearance with the commencing location. Just after removing with the solvent, the residue was neutralized with 3 N HCl to pH = three and extracted with ethyl acetate. The ethyl acetate extract was washed with brine, dried with MgSO4, and concentrated to pay for 38 mg (84 ) twenty. 1H NMR (CD3OD, four hundred MHz), 6.fifty seven (dd, J = two.0, 2.4 Hz, 1H), five.ninety three (dd, J = two.4, three.6 Hz, 1H), five.eighty (m, 1H), four.forty six (dd, J = seven.six, 5.two Hz, 1H), four.29 (dd, J = four.8, 7.six Hz, 1H), three.84 (t, J = seven.6 Hz, 2H), three.1-3.two (3H), 2.9 (dd, J = 12.four, four.eight Hz, 1H), 2.eighty five (t, J = seven.2 Hz, 2H), two.68-2.seventy one (d, J = 12.4 Hz, 1H), 2.61 (t, J = 7.2 Hz, 2H), two.19 (t, J = seven.two Hz, 2H), one.34-1.seven (14H). 13C NMR (CD3OD, a hundred MHz), 176.82 (CO), 175.97 (CO), 166.10 (CO), 132.00 (C), 121.22 (CH), 107.fifty two (CH), 106.08 (CH), sixty three.36 (CH), sixty one.60 (CH), 57.01 (CH), 47.19 (CH2), 41.03 (CH2), 40.22 (CH2), 36.82 (CH2), 34.48 PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/20569196 (CH2), 32.fifty four (CH2), thirty.30 (CH2), 29.78 (CH2), 29.fifty one (CH2), 27.62 (CH2), 27.forty four (CH2), 26.ninety five (CH2), 22.55 (CH2).
