Reexamination of Stereochemical Issues Concerning 2-Phenyl-1,2-dihydropyridine-Maleimide Cycloadditions

The reaction of N-acetyl- and N-(carbomethoxy)-2-phenyl-1,2-dihydropyridines 1d-e with maleimides 5a-c has been shown by chemical correlation and X-ray analysis to proceed with only endo-maleimide, anti-phenyl stereoselectivity, rather than via stereosele
