โœฆ Synopsis


The carboxylic acid antibiotic A-23187 (A) is a divalent cation ionophore which has been isolated from cultures of Streptomyces chartreusensis.' The structure and proposed absolute configuration2 have shown it to be one of a limited group of natural products, including oligomycin B3 and aplysiatoxin, 4 which contains the unusual 1,7-dioxaspiro[5.5]undecane ring
