supporting information, p. 2121 - 2126 (2015/09/15)
A variety of polysubstituted δ-lactones containing three or four stereocenters were prepared from various dialkyl 2-(3-oxo-1,3-diarylpropyl)malonates by a Barbier-type zinc-mediated allylation or cyclohexenylation of the keto group, followed by intramolec
The Michael addition of active methylene compounds to chalcone derivatives using a catalytic amount of iodine and K2CO3 at room temperature
Ren, Yi-Ming,Cai, Chun
experimental part, p. 176 - 178 (2011/07/31)
A convenient method for the Michael addition of active methylene compounds to chalcone derivatives has been developed using the inexpensive and environmentally friendly reagent I2/K2CO3 at room temperature. The method is m
1H and 13C NMR studies of some 1, 1 -bis(carbethoxy)-2-aryl-4-phenyl/(4- chlorophenyl)-4-oxobutane and their derivatives
Saravanan, Sivaperuman,Muthusubramanian, Shanmugam
experimental part, p. 917 - 922 (2010/10/18)
The 1H and 13C NMR spectral features of l, l-bis(carbethoxy)-2-aryl-4- phenyl/(4-chlorophenyl)-4-oxobutane la-j and their carbonyl derivatives 2a-e are discussed in the light of their diastereotopic characteristics and preferred conformational structures
Tetraethylammonium superoxide induced Michael addition of active methylene compounds to chalcones
Raghuvanshi, Raghvendra Singh,Singh, Krishna Nand
experimental part, p. 1161 - 1163 (2009/12/26)
Michael addition of active methylene compounds to chalcones using in-situ generated tetraethylammonium superoxide results in the formation of Michael adducts in 69-84% yield under mild reaction conditions, at room temperature.
