| 11. | Asymmetric Induction of the 1, 3-Dipolar Cycloaddition Reaction with Chiral Lewis Acid Catalysts
|
| 12. | The process is driven by dipolar coupling, and is therefore related to internuclear distances.
|
| 13. | Montr�alones participate in 1, 3-dipolar cycloaddition reactions with polyheterocycles related to polypyrroles.
|
| 14. | It also belongs to the class of dipolar aprotic solvents such as dimethylformamide and dimethyl sulfoxide.
|
| 15. | We thus observe no dipolar coupling.
|
| 16. | In this compound the dipolar structure is calculated to contribute 23 % to the total structure.
|
| 17. | The units are dipolar, which means that they produce sound both in front and behind equally.
|
| 18. | 1, 3-dipolar cycloaddition with nitrile oxides is a widely used masked-aldol reaction.
|
| 19. | Subsequent 1, 3-dipolar cycloaddition reaction occurs through a transient metal-complexed carbonyl ylide.
