Usage

Description

Taxusin is a taxane diterpenoid, specifically a taxa-4(20),11-diene, in which the 5α, 9α, 10β, and 13α hydrogens have been replaced by acetoxy groups. It is a prominent secondary metabolite found in the heartwood of certain plants, particularly those belonging to the Taxus genus.

Uses

Used in Pharmaceutical Industry:
Taxusin is used as a pharmaceutical compound for its potential anticancer properties. It has been found to exhibit cytotoxic effects on various cancer cell lines, making it a promising candidate for the development of new cancer treatments.
Used in Drug Delivery Systems:
Similar to gallotannin, taxusin can also be incorporated into drug delivery systems to enhance its bioavailability and therapeutic outcomes. By using various organic and metallic nanoparticles as carriers, the delivery, efficacy, and targeting of taxusin to cancer cells can be improved.
Used in Traditional Medicine:
Taxusin, being a secondary metabolite of plants, has been used in traditional medicine for its potential therapeutic properties. It may be utilized in the formulation of herbal remedies and supplements, particularly those aimed at cancer treatment and prevention.
Used in Chemical Research:
As a taxane diterpenoid, taxusin is an important compound for chemical research and development. It can be used as a starting material for the synthesis of other bioactive compounds or as a reference compound in the study of the chemical properties and mechanisms of action of taxane diterpenoids.

Enantioselective total synthesis of (+)-taxusin

For the total synthesis of (+)-taxusin, the AC-ring fragment 8 was prepared from an optically active 2-bromo-3-siloxycyclohexenecarbacetal 5 via 4 steps and was converted to the dienol silyl ether 13. The thus-obtained 13 underwent B-ring cyclization in the presence of Me2AlOTf to produce the ABC endo-tricarbocycle 14 having C9α, C10β-substituents, which was converted to the cyclopropyl ketone 21a. Introduction of C19 methyl via reductive cleavage of the cyclopropane ring under Birch conditions and successive in situ treatment of the resulting enol with methanol gave the C3α-protonated ketone 24. Next, 24 was converted to the allylsilane 29, which was then oxidized with m-CPBA to produce the fully functionalized taxusin carbon skeleton. Finally, removal of the silyl protecting groups followed by acetylation completed the total synthesis of (+)-taxusin.
