| Spirastrellolide A was isolated from marine sponge Spirastrellolide coccinea by Roberge et. al. in 2003. Spirastrellolide A was found not only to cause premature entry into mitosis and mitotic arrest in cells, but also to exhibit inhibitory activity of protein phosphatase PP2A (IC50 = 1 nM) along with a good selectivity for PP2A over PP1 (IC50 = 50 nM). Our synthesis of the C11-C23 fragment of Spirastrellolide A will be described in the presentation, which features a ketal – tethered RCM as an alternative approach to the construction of spiroketals. |
