Diversity-Oriented Synthesis of Polyketide Natural Products via Iterative Chemo- and Stereoselective Functionalization of Polyenoates: Development of a Unified Approach for the C(1−19) Segments of Lituarines A−C
摘要:
A unified, stereocontrolled synthesis of the C(1-19) segments of the lituarines A-C (1-3) has been achieved, highlighted by application of an iterative chemo- and stereoselective trienoate functionalization protocol, a strategy that holds considerable promise for the diversity oriented synthesis of polyketides.

π-system. This carbonate reacted fast enough to avoid scrambling and formation of symmetric bisallyl tetronicacids. The 3-allyl-3-penta-2,4-dienyltetronic acid thus obtained is a key intermediate en route to the natural spirolactone bakkenolide A. allylation - regioselectivity - palladium -tetronicacid- Schlosser-Wittig reaction
