The 1,3-dipolar cycloaddition reaction of azomethine ylides generated in situ by isatin and L-proline to acrylonitrile and methyl acrylate in water affords a series of spirooxindolo pyrrolizidines in good yields. [ABSTRACT FROM AUTHOR]

This new method provides access to phthalides by reaction of benzoic acids with vinyl ethyl ketone, methyl acrylate, N,N-dimethylacrylamide, ethyl and phenyl vinyl sulfones with interesting regio- and chemoselectivity though often in moderate yields only. [ABSTRACT FROM AUTHOR]

1-Alkyl-3-diazoindol-2-ones react with chalcones, dimethyl fumarate, or methyl acrylate providing the title compounds in good yields with remarkable diastereoselectivities and regioselectivities in the case of unsymmetrically substituted chalcones. [ABSTRACT FROM AUTHOR]

Some of the title compounds (III), synthesized via a Pictet-Spengler reaction, are found to be cytotoxic against prostate, lung, breast, and cervical cancer cell lines. [ABSTRACT FROM AUTHOR]

An enantioselective Diels-Alder reaction of 2,4-dienols and methyl acrylate is developed using a chiral Zn(II)/Mg(II) octahydro-BINOL complex as catalytic system. [ABSTRACT FROM AUTHOR]

The article presents chemical equations related to the article "Synthesis of Di-, Tri-, and Tetrasubstituted Pyridines from (Phenylthio)carboxylic Acids and 2-[Aryl(tosylimino)methyl]acrylates" by L. Zhang and others, published in the journal "Organic Letters" in 2014.

Reaction of α,β-unsaturated ketones with a slight excess of an equimolar mixture of BBr3 or BCl3 and ethylene glycol offers a straightforward synthesis of β-haloketones. [ABSTRACT FROM AUTHOR]

The starting compounds for these lactonization reactions are prepared in a three step procedure from methyl acrylate. [ABSTRACT FROM AUTHOR]
