Some Observations Concerning the Lactonization of 3-Aroylpropionic Acids
Tsolomitis, A.,Sandris, C.
, p. 1545 - 1548 (2007/10/02)
The ease of lactonization og the γ-keto acids ArCOCH2CH2COOH is shown to depend on the nature of the aryl group: the presence of electron-releasing substituents on the aryl group results in a more rapid reaction as compared to the presence of electron-wit
Improved Synthesis of 3-Aralkylidine-5-arylthiophen-2-(3H)ones
Miller, Gerald A.,Heindel, Ned D.,Minatelli, John A.
, p. 1253 - 1254 (2007/10/02)
3-Aralkylidene-5-arylthiophen-2-(3H)ones can be prepared in two steps from 4-aryl-4-oxobutanoic acids through the intermediacy of butenolides and thiophenones generated by the sequential action of acetic anhydride, sodium hydrosulfide and aromatic aldehyd
