Uses for Akanocure Stereotetrad Lactones 5b: Full Lactone Reductions

One of PolySciTech’s latest product offerings is Akanocure stereotetrad lactones ( for use as synthetic precursors. There are many potential reactions for these lactones which can result in a wide array of useful molecules. In this series of postings, we will highlight potential uses of these materials. One potential usage is the full reduction of the lactone. This reaction has been utilized in the past to provide for synthesis of (+)-neopeltolide fragments, a chemotherapeutic agent. This research holds promise for improved availability of chemotherapeutic agents. Read more: Mineeva, I. “New approach to the synthesis of macrocyclic core of cytotoxic lactone (+)-neopeltolide. Synthesis of CC segment basing on cyclopropanol intermediates.” Russian Journal of Organic Chemistry 51, no. 8 (2015).

“A new retrosynthetic procedure was developed for the synthesis of the macrocyclic core of a cytotoxic lactone (+)-neopeltolide utilizing cyclopropanol intermediates. The synthesis was suggested and carried out of the C7–C16 segment of (+)-neopeltolide to obtain (4S,6S)-6-[(2S)-2-hydroxypentyl]-4-methyltetrahydro-2H-pyran-2-one. The possibility was demonstrated of a formal synthesis based on the obtained product of the potential antitumor pharmaceutical (+)-neopeltolide.”
