80155-95-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 80155-95-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,1,5 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80155-95:
(7*8)+(6*0)+(5*1)+(4*5)+(3*5)+(2*9)+(1*5)=119
119 % 10 = 9
So 80155-95-9 is a valid CAS Registry Number.

Carbene-Catalyzed Formal [5 + 5] Reaction for Coumarin Construction and Total Synthesis of Defucogilvocarcins

Huang, Xuan,Zhu, Tingshun,Huang, Zhijian,Zhang, Yuexia,Jin, Zhichao,Zanoni, Giuseppe,Chi, Yonggui Robin

, p. 6188 - 6191 (2017)

An N-heterocyclic carbene-catalyzed formal [5 + 5] reaction between enals and furanones that generates multisubstituted coumarins in a single step is reported. Five atoms in each of the substrates are involved in this catalytic process to form a benzene and a lactone ring. The power of the method is further demonstrated in metal-free total syntheses of several natural products (defucogilvocarcins M, E, and V) bearing coumarin as the key structural motif.

An inverse electron demand Diels-Alder-based total synthesis of defucogilvocarcin V and some C-8 analogues

Nandaluru, Penchal Reddy,Bodwell, Graham J.

, p. 8028 - 8037,10 (2020/10/15)

A concise total synthesis of defucogilvocarcin V is reported. The key features of the approach are the formation of the C-ring using a vinylogous Knoevenagel/transesterification reaction and construction of the D-ring by way of an inverse electron demand Diels-Alder-driven domino reaction. The resulting C-8 ester functionality provides a handle for the synthesis of defucogilvocarcin V as well as some C-8 analogues from a common late-stage intermediate.

Combined directed metalation-cross coupling strategies. Total synthesis of the aglycones of gilvocarcin V, M and E

James, Clint A.,Snieckus, Victor

, p. 8149 - 8152 (2007/10/03)

Using the versatile Directed ortho and remote Metalation protocols linked with Suzuki-Miyaura cross coupling, efficient syntheses of defucogilvocarcin V, M, and E, 2-4 have been achieved.
