Popis: | The intramolecular dipolar cycloadditions of nitrones derived from aldehydes (8) and (14) were found to proceed with a high degree of diastereoselectivity. By taking advantage of the functionality and stereochemical features residing in the cycloadducts (10) and (11), respectively, the two novel vitamin D 2 derivatives (1c) and (1d) were synthesized |
