17-Allylamino-17-demethoxygeldanamycin (17-AAG)1 is a semisynthetic inhibitor of the 90 kDa heat shock protein (Hsp90) currently in clinical trials for the treatment of cancer. However, 17-AAG faces challenging formulation issues due to its poor solubility. Here we report the synthesis and evaluation of a highly soluble hydroquinone hydrochloride derivative… (More)
[reaction: see text] Nucleophilic 1,2-addition of lithiated glycal 9b to functionalized quinone 7 provided, after reductive aromatization, C-arylglycoside 11b. Treatment with mCPBA afforded the tricyclic papulacandin framework. Alternatively, hydroboration gave the chaetiacandin nucleus.
Calculations of third-harmonic generation in conditions of coherent two-photon propagation in lithium vapor are presented that predict shapes, frequencies, and intensities for the fundamental pulse yielding an optimal third-harmonic energy conversion efficiency of 8%.
