## Abstract The 2βcarbon units, glycine and glyoxylate are combined by a mild reaction via the copper chelate of glycine. The resulting Ξ²βhydroxy aspartic acid is converted to DLβmalic acid by means of hydroxylamine 0βsulfonic acid. The overall yields are in the range of 35β50% in submillimolar pre

A new synthesis of the 2-dimethylamino-4-hydroxy-6-methoxymethyl-3H-imidazo [4', 5' :3,4] pyfido[2,3-b]indole, used as key intermediate in the total synthesis of the alkaloids grossularines -1 and -2. based on the step-wise formation of the pyfidine and imidazole tings, is described.
Treatment of the dimethyl acetals of citral (1) and farnesal be subjected to a Diels-Alder reaction, which allows further synthetic elaboration. In particular, in the case of farnesal (2) with the superbase "LICKOR" in THF at low temperatures induces regioselective metallation at the allylic methyl
