Technical Notes:
1.The preparation of binaphthol monophosphoric acid derivatives.
2.Organocatalyst developed for the diastereo- and enantioselective 1 4-conjugate addn. of a variety of
ß-ketoesters to nitroolefins, employed in the addn. re action, providing the corre sponding nitroalkanes in high yield (up to 97%) with moderate diastereoselectivities (up to 2.6:1 dr) and enantioselectivities (up to 58% ee).
