99790-15-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 99790-15-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,9 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99790-15:
(7*9)+(6*9)+(5*7)+(4*9)+(3*0)+(2*1)+(1*5)=195
195 % 10 = 5
So 99790-15-5 is a valid CAS Registry Number.

N-carbamate protected amino acid derived guanidine organocatalysts

Al-Taie, Zahraa S.,Anderson, Joseph M.,Bischoff, Laura,Christensen, Jeppe,Coles, Simon J.,Froom, Richard,Gibbard, Mari E.,Jones, Leigh F.,de Kleijne, Frank F.J.,Murphy, Patrick J.,Thompson, Emma C.

, (2021)

We report the preparation of a range of N-protected amino acid derived guanidine organocatalysts and their application to the Michael addition of 2-hydroxy-1,4-napthoquinone to β-nitrostyrene, achieving a maximum ee of 26%. Whilst these catalysts gave poo

A rapid and efficient one-pot method for the reduction of N-protected α-amino acids to chiral α-amino aldehydes using CDI/DIBAL-H

Ivkovic, Jakov,Lembacher-Fadum, Christian,Breinbauer, Rolf

supporting information, p. 10456 - 10460 (2015/11/10)

N-Protected amino acids can be easily converted into chiral α-amino aldehydes in a one-pot reaction by activation with CDI followed by reduction with DIBAL-H. This method delivers Boc-, Cbz- and Fmoc-protected amino aldehydes from proteinogenic amino acids in very good isolated yields and complete stereointegrity.

Total synthesis of halipeptins A and D and analogues

Nicolaou,Kim, David W.,Schlawe, Daniel,Lizos, Dimitrios E.,De Noronha, Rita G.,Longbottom, Deborah A.

, p. 4925 - 4929 (2007/10/03)

(Chemical Equation Presented) Deceptive rings: Halipeptins A (1 a) and D (1 b) and analogues thereof were synthesized from fragments 2 and 3 a, b, respectively. Key steps included peptide-bond formation, DAST-induced thiazoline construction, and macrolact
