Selectivity was determined by analysis of the crude 1H NMR spectra. d 1 mL of CH2Br2 (0.2 M) was used, and the reaction was conducted for 24 h. e Isolated yields. f 10 equiv of CH2Br2 was used. g Reaction conducted in a sealed batch reactor (10-mL volume). h 20 equiv of H2O...
High resolution FAB-MS data indicated the molecular formula C30H44O5, which is consistent with the 13C NMR data. The 13C NMR spectrum exhibited thirty signals which were assigned as shown in Table 1 by analyses of DEPT and 2D PFG-HMQC2) ... T Sato,T Hanada,M Arioka,... - 《Journa...
