180692-68-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 180692-68-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,6,9 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 180692-68:
(8*1)+(7*8)+(6*0)+(5*6)+(4*9)+(3*2)+(2*6)+(1*8)=156
156 % 10 = 6
So 180692-68-6 is a valid CAS Registry Number.

Asymmetric synthesis of a 12-membered macrolactone core and a 6-epi analogue of amphidinolide W from 4-pentenoic acid

Chatterjee, Bhaskar,Mondal, Dhananjoy,Bera, Smritilekha

, p. 1170 - 1185,16 (2020/09/09)

A flexible and efficient asymmetric route to the synthesis of a 12-membered macrolactone core and a 6-epi analogue of amphidinolide W has been accomplished from commercially available 4-pentenoic acid. The successful generation of stereocenters was achieved by utilizing an Evans' chiral auxiliary-based alkylation and aldol reaction. Other key reactions such as a Julia-Kocienski olefination, Kita's macrolactonization, ring closing metathesis (RCM) reaction, and Yamaguchi's esterification were significant for the construction of the macrolactone cores.

Highly stereoselective approach toward the synthesis of the macrolactone core of amphidinolide W

Mohapatra, Debendra K.,Chatterjee, Bhaskar,Gurjar, Mukund K.

body text, p. 755 - 758 (2009/05/07)

The diastereoselective synthesis of the macrolactone core of amphidinolide W was successfully accomplished using Evans' asymmetric alkylation, Aldol reaction, Julia-Kocienski olefination, and Kita's macrocyclization protocol.

Synthesis of bistramide A

Statsuk, Alexander V.,Liu, Dong,Kozmin, Sergey A.

, p. 9546 - 9547 (2007/10/03)

We have developed an efficient and highly stereocontrolled synthesis of bistramide A, a selective activator of protein kinase C isotype δ. Our synthetic strategy featured a novel bidirectional approach for spiroketal construction based on the ring-opening
