The marineantibiotic korormicin, isolated from the culture filtrate of marine bacterial strain Pseudoalteromonas sp. F-420, specifically inhibits the growth of marine Gram-negative bacteria without affecting terrestrial species. The absolute configuration of korormicin was determined by the combination of a CD exciton chirality method and chemical degradation. Convergent total synthesis of koromicin

Possible diastereoisomers of korormicin were synthesized in a stereoselective manner, and the absolute stereochemistry of natural korormicin was elucidated by comparison of the reported [α]D value with the measured ones.
