Abstract:
:Two new bromophenols, (E)-3-(2,3-dibromo-4,5-dihydroxyphenyl)-2-methylpropenal (1) and 3-(2,3-dibromo-4,5-dihydroxyphenyl)-2-methyl-1-propanol (2), together with 11 known bromophenols (3-13), were isolated from the ethanolic extract of the brown alga Leathesia nana S. et G. Their structures have been elucidated by spectroscopic methods, including IR, MS, HRMS, 1D and 2D NMR techniques.
