151775-39-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 151775-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,7,7 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 151775-39:
(8*1)+(7*5)+(6*1)+(5*7)+(4*7)+(3*5)+(2*3)+(1*9)=142
142 % 10 = 2
So 151775-39-2 is a valid CAS Registry Number.

Macrolactonization-Transannular Aldol Condensation Approach to the Taxane AB Ring System

Chai, Ki-Byung,Sampson, Paul

, p. 6807 - 6813 (1993)

Cyclohexenone 13, containing the fully elaborated taxane A ring, was prepared from 4,4-dimethyl-2-cyclohexenone (43percent for four steps); two copper-catalyzed Grignard conjugate addition reactions on crowded dienones 8 and 11 were employed as key transformations.Elaboration of 13 to the chloro keto acid 6 was achieved via an epoxidation/regioselective chloride-mediated epoxide ring opening/Jones oxidation protocol (42percent for three steps).Macrolactonization (59percent) followed by chemoselective transannular aldol condensation within the resulting 11-membered bicyclic keto lactone 4 under thermodynamic control (51percent) resulted in closure of the taxane B ring to afford the target 2(5H)-furanone 3.
