Abstract
A regio- and stereoselective functionalization methodology of linear dicarboxylic acids has been developed and applied in the synthesis of paraconic acid natural products. Using this strategy, (-)-roccellaric acid 1a was prepared in 25% overall yield. The formal total synthesis of (-)-protolichesterinic acid 1b and (-)-methylenolactocin 1c has been accomplished starting from a differentially functionalized succinate 5.Keywords
