3721-21-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3721-21-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,2 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3721-21:
(6*3)+(5*7)+(4*2)+(3*1)+(2*2)+(1*1)=69
69 % 10 = 9
So 3721-21-9 is a valid CAS Registry Number.

Titanium and Cobalt Bimetallic Radical Redox Relay for the Isomerization of N -Bz Aziridines to Allylic Amides

Wood, Devin P.,Guan, Weiyang,Lin, Song

, p. 4213 - 4220 (2021/08/10)

Herein a bimetallic radical redox-relay strategy is employed to generate alkyl radicals under mild conditions with titanium(III) catalysis and terminated via hydrogen atom transfer with cobalt(II) catalysis to enact base-free isomerizations of N-Bz aziridines to N-Bz allylic amides. This reaction provides an alternative strategy for the synthesis of allylic amides from alkenes via a three-step sequence to accomplish a formal transpositional allylic amination.

Bifunctional asymmetric catalysis with hydrogen chloride: Enantioselective ring opening of aziridines catalyzed by a phosphinothiourea

Mita, Tsuyoshi,Jacobsen, Eric N.

body text, p. 1680 - 1684 (2009/12/03)

Ring opening of aziridines with hydrogen chloride to form β-chloroamine derivatives is catalyzed by a chiral phosphinothiourea derivative in high yields and with high enantioselectivities. On the basis of 31P NMR studies, activation of HCl appears to proceed via quantitative protonation of the catalyst to afford a phosphonium chloride complex. Georg Thieme Verlag Stuttgart.
