Towards the synthesis of calyculin: A synthetic intermediate corresponding to the C(26)-C(37) fragment

The synthetic intermediate 2 corresponding to the C(26)-C(37) fragment of calyculin A (1) has been synthesized. Key transformations include the efficient one-pot construction of the oxazole system embedded in 1 without epimerization α [C(30)] to the ring,
