Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
An addition reaction in which a cyclic molecule is formed.
- ‘Nitrone cycloaddition and retro-aldol reactions have also been applied to the total synthesis of morphine.’
- ‘Interplanar angles of 40.5 and 39 have been found in the 5-ethoxypsoralen-thymine and 5-butoxypsoralen-thymine photoproducts, respectively, where the cycloaddition occurs at the pyrone ring.’
- ‘These data confirm that cycloaddition occurs between the 8,9-double bond of HFQ and the 5,6-double bond of thymine.’
- ‘The photochemical reaction pathways of the different cycloadditions were explored on the basis of TD-DFT calculations using the Gaussian 98 implementation of the method developed by Scuseria and co-workers.’
