An improved synthesis of azedarachol.
Ran G, Weisheng T. Ran G, et al. Steroids. 2022 Oct;186:109072. doi: 10.1016/j.steroids.2022.109072. Epub 2022 Jun 20. Steroids. 2022. PMID: 35738310
An improved synthesis of azedarachol is reported in 10 steps with an overall yield of 12% from pregnanetriol. A proper use of p-anisaldehyde dimethyl acetal provided a chance of regioselective reduction of 2-enepregnane-16R,20R-p-anisaldehyde acetal(6) and in turn a …
