623935-92-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 623935-92-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,3,9,3 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 623935-92:
(8*6)+(7*2)+(6*3)+(5*9)+(4*3)+(3*5)+(2*9)+(1*2)=172
172 % 10 = 2
So 623935-92-2 is a valid CAS Registry Number.

Site-Specific Photochemical Desaturation Enables Divergent Syntheses of Illicium Sesquiterpenes

Desaturation of unactivated alkanes remains a challenging yet desirable strategy to make olefins. The Illicium sesquiterpenes usually possess highly oxygenated cage-like architectures, and some of them exhibit prominent neurotrophic effects. Here, we disclose a unique photochemical desaturation strategy for the efficient, highly stereocontrolled total syntheses of five Illicium sesquiterpenes from inexpensive (R)-pulegone, featuring a 13-step gram-scale synthesis of (-)-merrilactone A. The efficiency of the syntheses derives from an expedient construction of a tetracyclic framework via two annulations, a site-specific photoinduced single-step desaturation in a complex hydrocarbon system, and diverse oxygenation manipulations around the resultant olefin intermediate. This work highlights how late-stage desaturation can dramatically streamline the synthesis of complex terpenes and diverse non-natural analogues for establishing the structure-activity relationship and elucidating their molecular mechanisms of bioactivity.

Taber, Douglass F.,Bai, Sha,Tian, Weiwei

experimental part, p. 9733 - 9737 (2012/01/04)

A trisubstituted cyclopentane chiron has been prepared by dynamic kinetic reduction of a pulegone-derived β-keto ester. This chiron served as the starting material for the synthesis of the reported structure of the tricyclic sesquiterpene trans-africanan-
