17642-89-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17642-89-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,4 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17642-89:
(7*1)+(6*7)+(5*6)+(4*4)+(3*2)+(2*8)+(1*9)=126
126 % 10 = 6
So 17642-89-6 is a valid CAS Registry Number.

Reductive Alkylation of Tertiary Lactams via Addition of Organocopper (RCu) Reagents to Thioiminium Ions

Mateo, Pierre,Cinqualbre, Joséphine E.,Meyer Mojzes, Melinda,Schenk, Kurt,Renaud, Philippe

, p. 12318 - 12327 (2017/12/08)

A simple procedure for the conversion of tertiary lactams to 2-monoalkylated cyclic amines is described. The reaction sequence involves conversion of a lactam to a thioiminium ion followed by reaction with an organocopper (RCu) reagent and final reduction with triacetoxyborohydride. The reaction is high yielding and shows an excellent functional group tolerance. Its utility is demonstrated by a rapid synthesis of indolizidine 167B. The excellent chemoselectivity of the process, where only monoalkylation products are formed, is rationalized by a mechanism involving the formation of a transient enamine.

Studies on the Eschenmoser coupling reaction and insights on its mechanism. Application in the synthesis of Norallosedamine and other alkaloids

Neto, Brenno A.D.,Lapis, Alexandre A.M.,Bernd, Alinne B.,Russowsky, Dennis

experimental part, p. 2484 - 2496 (2009/08/07)

The conditions of the Eschenmoser coupling reaction were studied. The formation of the α-thioiminium ion was achieved faster in the presence of an additive (NaI) and dry chloroform as the preferred solvent. The developed conditions were used for the second part of the reaction (the sulfur extrusion itself). The present protocol avoids the formation of byproducts, which were previously described as a major drawback to be overcome. Electrospray ionization tandem mass spectrometry was used to characterize some aspects (intermediates) of the first step of the reaction mechanism. Some reduction conditions were properly tested and the selected conditions were applied to the synthesis of the natural alkaloid Norallosedamine and other derivatives.
