78469-77-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78469-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,4,6 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 78469-77:
(7*7)+(6*8)+(5*4)+(4*6)+(3*9)+(2*7)+(1*7)=189
189 % 10 = 9
So 78469-77-9 is a valid CAS Registry Number.

Total Synthesis of the Echinodermatous Ganglioside LLG-3 Possessing the Biological Function of Promoting the Neurite Outgrowth

Huang, Yuahn-Sieh,Shih, Jing-Feng,Tsai, Yow-Fu,Wu, Yu-Fa

supporting information, p. 7491 - 7495 (2020/10/09)

A total synthesis of echinodermatous ganglioside LLG-3 with neuritogenic activity was accomplished by a convergent strategy. The synthesis of 2-hydroxyethyl 8-O-Me-α-sialoside 2 was started from the phenyl 7,8-di-O-Pico-thiosialoside 5, which can be chemoselectively removed the picoloyl group, and then the methyl group in 8-O-MeNeu5Ac moiety was chemoselectively prepared using TMSCHN2/FeCl3. For preparation of the terminal disialic unit, oxidative amidation was initially utilized by our group to efficiently construct the α(2,11) linkage of 8-O-Me-Neu5Acα(2,11)Neu5Gc. Herein, we also demonstrate that the synthesized ganglioside LLG-3 exhibited the neuritogenic activity toward the primary cortical neurons and that biological activity is superior to that of ganglioside DSG-A.

Stereoselective Synthesis of the C27-C35 Eribulin Fragment and Its Utilization in Building Structurally Diverse Macrocycles

Konda, Saidulu,Khatravath, Mahender,Mallurwar, Naveen Kumar,Rao, Pallavi,Sripelly, Shivashankar,Iqbal, Javed,Arya, Prabhat

, p. 1663 - 1683 (2016/05/24)

A practical and scalable stereoselective synthesis of the western substituted tetrahydrofuran ring C27-C35 fragment of eribulin was developed by using (2S,3S)-tartaric acid as a cheap starting material that was converted into an intermediate through a stereoselective vinylation and cross-metathesis as the key steps. A regio-and stero-selective intramolecular oxy-Michael cyclization or an iodocyclization reaction finally provided the required western tetrahydrofuran ring fragment and its related isomeric analogues. These key fragments were further utilized in obtaining several types of macrocyclic derivatives for exploration of their biological properties. The simplicity of our present approach has the potential to be considered for large-scale syntheses of key fragments of eribulin and related analogues.

A facile approach for the synthesis of C13-C24 fragments of maltepolides A, C and D

Rao, P. Sankara,Srihari

, p. 9629 - 9638 (2016/10/22)

A linear, chiron approach for the synthesis of C13-C24 fragments of cytostatic maltepolides A, C and D consisting of a tetrahydrofuran subunit and a chiral alkenyl/alkyl substituent is achieved from (+)-diethyl l-tartrate. The other chiral stereocenters were generated by employing key reactions such as Crimmins aldol, alkynylation and CeCl3·7H2O mediated Luche reduction reactions.
