英文摘要A novel ureidobromophenol, rhodomelin A (1), was characterized from?Rhodomela confervoides. Its structure was elucidated by spectroscopic analysis. Both enantiomers of?1?were synthesized using a convergent strategy starting from?d/l-pyroglutamic acids, respectively, allowing assignment of the?R-configuration for the naturally occurring isomer by chiral HPLC analysis. Rhodomelin A represents the first example of a naturally occurring ureidopyrrolidone alkaloid incorporating a γ-aminobutyric acid unit. The scavenging activity of?1?toward DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonate)) radicals was assayed.
