Studies on tumor promoters. 11. A new [5+2] cycloaddition method and its application to the synthesis of BC ring precursors of phorboids
摘要:
A new method for the generation of oxidopyrylium zwitterions has been developed that allows for its use in the [5 + 2] cycloaddition of substrates incorporating thermally unstable functionalities, providing for the synthesis of previously inaccessible precursors to tiglianes, daphnanes, and ingenanes.
