Asymmetric synthesis of 2-alkyl-3-phosphonopropanoic acids via P - C bond formation and hydrogenation
Badkar, Pallavi A.,Rath, Nigam P.,Spilling, Christopher D.
, p. 3619 - 3622 (2007)
Allylic acetates, formed by the acetylation of Baylis Hillman adducts, undergo addition of phosphorus nucleophiles to give stereoselectively the Z-unsaturated esters. TFA cleavage of the fert-butyl ester and asymmetric hydrogenation of the unsaturated aci
Unprecedented E-stereoselectivity on the sigmatropic Hurd-Claisen rearrangement of Morita-Baylis-Hillman adducts: A joint experimental-theoretical study

Herein we report the first systematic investigation of the tandem mercury(ii) catalysed transvinylation/Hurd-Claisen rearrangement of MBH adducts derived from alkyl acrylates. This is the first report of E-selectivity for MBH adducts with alkyl side chain
Direct Synthesis of Dihydropyrrolo[2,1-a]Isoquinolines through FeCl3 Promoted Oxidative Aromatization
Cui, Hai-Lei,Jiang, Lu,Tan, Hao,Liu, Si
supporting information, p. 4772 - 4780 (2019/10/28)
We have developed a straightforward FeCl3 promoted synthesis of dihydropyrrolo[2,1-a]isoquinolines through formal (3+2) cycloaddition/oxidative aromatization cascade of dihydroisoquinoline with Morita-Baylis-Hillman carbonates (up to 96% yield)
The Baylis-Hillman reaction: Rate acceleration in silica gel solid phase medium
Basavaiah,Reddy
, p. 985 - 988 (2007/10/03)
Remarkable rate acceleration in the Baylis-Hillman reaction of aromatic aldehydes with acrylates, particularly tertbutyl acrylate, in silica gel solid phase medium has been described.
Preparation and Selected Reactions of t-Butyl 2-Methylene-3-oxoalkanoates
Hoffmann, H. Martin R.,Gassner, Andreas,Eggert, Ulrike
, p. 2475 - 2480 (2007/10/02)
The title class of 1,1-diactivated ethylenes has been prepared in two steps from aldehydes and t-butyl acrylate by (i) DABCO-catalyzed coupling to give t-butyl 2-(hydroxyalkyl)-2-propenoates 11 and (ii) low-temperature Jones oxidation, followed by swift work up at low temperature.The resulting butyl 2-methylene-3-oxoalkanoates 12 are stabilized by sterically demanding and also by aromatic groups R.For primary unhindered alkyl groups, stability is low.The compounds enter into Michael reactions, hetero Diels-Alder additions with enol ethers, and self-dimerization.Key Words: Ethylenes, 2,2-diactivated/ Michael acceptors/ 1-Oxa-1,3-butadienes/Hetero Diels-Alder reaction
