Tetrahedron Letters, 35, p. 379, 1994 DOI: 10.1016/0040-4039(94)85058-5

General Description

N-(tert-Butoxycarbonyl)-p-toluenesulfonamide is a N-substituted sulphonamide and its reaction with N-trityl L-serine esters under Mitsunobu reaction conditions is reported. It can be directly coupled with primary, secondary and allylic alcohols under Mitsunobu conditions to afford various sulfonyl-protected amines.

Check Digit Verification of cas no

The CAS Registry Mumber 18303-04-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,0 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18303-04:
(7*1)+(6*8)+(5*3)+(4*0)+(3*3)+(2*0)+(1*4)=83
83 % 10 = 3
So 18303-04-3 is a valid CAS Registry Number.

Synthesis, catalytic activity and redox properties of palladium(0) complexes with 15-membered triolefinic macrocyclic ligands containing one, two or three ferrocenyl groups

Llobet, Antoni,Masllorens, Ester,Moreno-Ma?as, Marcial,Pla-Quintana, Anna,Rodríguez, Montserrat,Roglans, Anna

, p. 1425 - 1428 (2002)

A series of 15-membered triolefinic macrocycles containing ferrocenyl groups and their palladium(0) complexes have been synthesized and characterized. Their catalytic activity has been demonstrated in Suzuki-type cross-coupling and in the Heck reaction. Their redox properties have been investigated by means of cyclic voltammetry.

DirectN-glycosylation of tosyl and nosyl carbamates with trichloroacetimidate donors

Khanam, Ariza,Mandal, Pintu Kumar

supporting information, p. 15386 - 15391 (2021/09/07)

Under catalyst and additive-free conditions, a convenient and highly efficient eco-friendly method for the stereoselective synthesis ofN-glycofuranosyl and glycofuranosyl sulfonamides has been developed. The two-component reaction of glycofuranosyl trichloroacetimidates with a wide range of tosyl and nosyl carbamate acceptors having varying pKa-values including non-sugar-, and sugar-derived carbamates as well as amino acid-derived carbamates, proceeded smoothly with good yield and β-stereoselectivity. In addition, the selective deprotection ofN-carbamates andN-sulfonyl groups of theN-glycoside functioning as orthogonal protective groups was performed for further functionalization of theN-glycosides.
