The planar structure of a newly reported group of bacterial sulfur-containing aminolipids was revised and their absolute configuration determined by a combination of analytical techniques, isolation, degradation experiments, and total synthesis. The revised structures, termed cysteinolides, diverge from previous homotaurine-based proposals, revealing a composition of a cysteinolic acid containing head
