摘要

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 ...
