An Effective Synthesis of Previously Unknown 7-Aryl Substituted Paullones

Molecules, 2023
A straightforward three-step procedure affording a wide range of novel 7-aryl substituted paullone derivatives was developed. This scaffold is structurally similar to 2-(1H-indol-3-yl)acetamides—promising antitumor agents—hence, could be useful for the ...

N-(4-Isopropoxyphenyl)acetamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2009
In the mol-ecule of the title compound, C(11)H(15)NO(2), the planar acetamide unit [maximum deviation of 0.0014 (6) Å] is oriented at a dihedral angle of 19.68 (4)° with respect to the aromatic ring. An intra-molecular C-H⋯O inter-action results in the formation of a six-membered ring. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link

N-(3-Chlorophenyl)acetamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2008
The conformation of the N-H bond in the structure of the title compound (3CPA), C(8)H(8)ClNO, is anti to the meta-chloro substituent, in contrast to the syn conformation observed for the ortho-chloro substituent in N-(2-chloro-phen-yl)acetamide, syn to both the ortho and meta chloro substituents in N-(2,3-dichloro-phen-yl)acetamide, and syn to the ...
