24438-49-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24438-49-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,4,3 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 24438-49:
(7*2)+(6*4)+(5*4)+(4*3)+(3*8)+(2*4)+(1*9)=111
111 % 10 = 1
So 24438-49-1 is a valid CAS Registry Number.

SYNTHESIS OF DEUTERATED ALDEHYDES

-

Paragraph 00194, (2021/03/13)

Described are methods for preparing a deuterated aldehyde using N-heterocyclic carbene catalysts in a solvent comprising D2O. The methods may be used to convert a wide variety of aldehydes (e.g., aryl, alkyl, or alkenyl aldehydes) to C-1 deuterated aldehydes under mild reaction conditions without functionality manipulation.

Coupling and cyclization of O-iodoanilines and propargylic bromides via allenes: An efficient entry to indomethacin

Zhu, Can,Ma, Shengming

, p. 2782 - 2785 (2013/07/19)

A sequential allene synthesis and cyclization has been realized in a one-pot manner. A Pd(0)-catalyzed one-pot reaction of N-Ts or -Ms 2-iodoanilines and propargylic bromides afforded indoles with pharmaceutical importance highly efficiently with diversity via sequential carbon-carbon bond coupling forming allenes and azapalladation. With this newly established methodology, an efficient approach to indomethacin, an anti-inflammatory drug (NSAID), has been accomplished.

Modified McFadyen-Stevens reaction for a versatile synthesis of aliphatic/aromatic aldehydes: Design, optimization, and mechanistic investigations

Iwai, Yuri,Ozaki, Takashi,Takita, Ryo,Uchiyama, Masanobu,Shimokawa, Jun,Fukuyama, Tohru

, p. 1111 - 1119 (2013/06/04)

The traditional McFadyen-Stevens reaction requires harsh alkaline reaction conditions, thus precluding application to the synthesis of aliphatic aldehydes. Our modified McFadyen-Stevens reaction enables the transformation from the N,N-acylsulfonyl hydrazine to the corresponding aldehyde upon treatment with an imidazole-TMS imidazole combination without relying on oxidative or reductive reagents. The reduced basicity and in situ protection of the resulting aldehyde widens the substrate scope to include aliphatic aldehydes, even ones bearing an α-hydrogen atom. Close examination of the side reactions for particular substrates in combination with theoretical considerations via DFT calculations led to a mechanistic understanding of the McFadyen-Stevens reaction involving an acyl diazene and a hydroxy carbene as reasonable intermediates.
