Abstract
An efficient construction of a suitably functionalized trisoxazole derivative related to telomestatin was developed from l-serine, which involved three sequential oxazoline cyclization-oxidation steps in an overall yield of 11% in a linear sequence of twelve steps.
Key words

Although the chirality of serine is destroyed in subsequent steps we preferred to use l-serine to avoid diastereomeric problems.
