Studying the Morita-Baylis-Hillman Reaction in Continuous Flow Using Packed Bed Reactors
Verdier, Rasmus A. T.,Mikkelsen, Jesper H.,Lindhardt, Anders T.
, p. 1524 - 1533 (2018)
Conditions for the Morita-Baylis-Hillman reaction were developed under continuous flow using a packed bed reactor carrying 4-(dimethylamino)pyridine immobilized on silica. High reaction rates were obtained, as the packed bed reactor mimics super-stoichiom

A phosphine-catalyzed [3 + 2] annulation of Morita-Baylis-Hillman (MBH) carbonates with 3-methyl-4-nitro-5-styrylisoxazoles has been developed to afford various multifunctional isoxazoles in moderate to good yields with moderate to excellent diastereoselectivities. With a spirocyclic chiral phosphine as the catalyst, up to 89% ee was obtained.
Phosphine-catalyzed [3+2] cycloaddition of Morita—Baylis—Hillman carbonates to isothiocyanates in the synthesis of adamantane-containing trisubstituted aminothiophenes
Abel, A. S.,Averin, A. D.,Beletskaya, I. P.,Butov, G. M.,Zenkov, I. S.
, p. 880 - 884 (2021/06/07)
An addition of the Morita—Baylis—Hillman (MBH) carbonates to adamantane-containing isothiocyanates was studied. The MBH carbonates react with 1-(4-isothiocyanatophenyl)-adamantane in the presence of triphenylphosphine to give 5-aryl-substituted adamantane
Synthesis of β-Lactams via Enantioselective Allylation of Anilines with Morita-Baylis-Hillman Carbonates
Krieck, Sven,Lange, Markus,Schüler, Philipp,Vilotijevic, Ivan,Westerhausen, Matthias,Zi, You

Enantioenriched β-lactams are accessed via enantioselective allylation of anilines with Morita-Baylis-Hillman carbonates followed by a base-promoted cyclization. The resulting 3-methyleneazetidin-2-ones are amenable to diastereoselective functionalization
Azidophosphonium salt-directed chemoselective synthesis of (E)/(Z)-cinnamyl-1H-Triazoles and regiospecific access to bromomethylcoumarins from Morita-Baylis-Hillman adducts
Karthikeyan, Soundararajan,Shobana, Radha Krishnan,Subimol, Kamarajapurathu Raju,Helen Ratna Monica,Kumar, Ayyanoth Karthik Krishna
, p. 1579 - 1587 (2020/09/16)
The direct transformation of Morita-Baylis-Hillman (MBH) adducts into molecules of interest is a crucial process wherein allylic hydroxy-protected or halogenated MBH adducts are commonly preferred. Herein, we report an azidophosphonium salt (AzPS)-catalys
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)
Regioselective dehydroxytrifluoromethylthiolation of allylic and propargylic alcohols with AgSCF3
Liu, Yin-Li,Xu, Xiu-Hua,Qing, Feng-Ling
supporting information, p. 953 - 956 (2019/03/07)
The reaction of easily available Morita–Baylis–Hillman (MBH) alcohols with AgSCF3 in the presence of n-Bu4NI and KI affords primary allylic SCF3 products in high yields and excellent regioselectivities. This regioselective dehydroxytrifluoromethylthiolation protocol could also be extended to propargylic alcohols for the preparation of the primary propargylic SCF3 products.
Latent Nucleophiles in Lewis Base Catalyzed Enantioselective N-Allylations of N-Heterocycles
Zi, You,Lange, Markus,Schultz, Constanze,Vilotijevic, Ivan
supporting information, p. 10727 - 10731 (2019/07/09)
Latent nucleophiles are compounds that are themselves not nucleophilic but can produce a strong nucleophile when activated. Such nucleophiles can expand the scope of Lewis base catalyzed reactions. As a proof of concept, we report that N-silyl pyrroles, i
Enantioselective dearomative [3+2] cycloaddition of 2-nitrobenzofurans with aldehyde-derived Morita-Baylis-Hillman carbonates
Yang, Xin-He,Li, Jian-Ping,Wang, Dong-Chao,Xie, Ming-Sheng,Qu, Gui-Rong,Guo, Hai-Ming
supporting information, p. 9144 - 9147 (2019/08/07)
The phosphine-catalyzed asymmetric dearomative [3+2] cycloaddition of 2-nitrobenzofurans with aldehyde-derived Morita-Baylis-Hillman (MBH) carbonates or allenoate was developed. The reaction with MBH carbonates resulted in a series of cyclopentabenzofurans containing three contiguous stereocenters with good to high yields, diastereoselectivities and enantioselectivities. The use of allenoate also gave the target product with moderate enantioselectivity.
