Abstract
Michael-addition of nitromethane anion to 5-ylidene-1,3-dioxane-4-ones 2 gives high yields of 5-(beta-nitroalkyl)-1,3-dioxane-4-ones 3 and 4 with a preponderance of 3 (re-attack). Hydrogenation of the products in the presence of Raney-Ni affords optically active 4-substituted cis -3-(alpha-hydroxyethyl)-pyrrolidine-2-ones 6. (C) 1997 Elsevier Scienc e Ltd.
