 note = {We achieved the first total synthesis of a novel (+/-)-6'-methoxyretrojusticidin B, which was proposed as procumphthalide A, utilizing regiocontrolled benzannulation of an aryl(aryl')-2,2-dichlorocyclopropylmethanol as the key step. (1)H NMR spectral data suggested that the structure of the synthesized product, 6'-methoxyretrojusticidin B, was inconsistent with that of natural procumphthalide A. A computational study of the rotational barrier rationally supports the existence of a rigid chiral axis in 6'-methoxyretrojusticidin B. The revised structural elucidation of natural procumphthalide A was concluded to be 5'-methoxyretrochinensin., Article, SYNLETT. 2010(15):2275-2278 (2010)},
