The first synthesis of (+)-crocacin C (3) in optically pure form is achieved following a convergent strategy. The synthesis also establishes the absolute stereochemistries of this novel class of potent antifungal and highly cytotoxic compounds. The naturally occurring crocacin C has (6S,7S,8R,9S) configuration, which is also the same for other congeners of the family, crocacins A, B and D.

The total synthesis of potent antifungal and cytotoxic agent (+)-crocacin C in optically pure form following a convergent strategy is described here in detail. The synthesis also established the absolute stereochemistry of the molecule having a (6S,7S,8R,9S) configuration. While C8 and C9 stereocenters were built following a Ti(IV)-mediated diastereoselective 'non-Evans' aldol reaction based on 2-oxazolidinethione chiral auxiliary, lithium dimethylcuprate opening of a C6-C7 chiral epoxide prepared by Sharpless epoxidation method established the remaining two stereocentres.
