1-diazo-2-oxoheptadecane, for example, the products of these two reactions are heptadecanoic acid and a surface-grafted long-chain ester. The latter can be removed as methyl heptadecanoate by ester exchange using methanolic HCl. Pronounced differences were observed between alumina, silica gel and fumed silica as supports, and were attributed to differences in the amount of adsorbed H2O and in the density of surface

Etude dela photochimie d'uneseriede composes tensioactifs diazoiques ou azoturo, dans des couches monomoleculaires a l'interface air-eau. L'irradiation d'α-diazocetones a longue chaine avec un rayonnement UV conduit a une perte rapide d'azote. Les cetenes formes reagissent avec la phase support pour donner des acides carboxyliques et se dimerisent avec formation de β-lactones, en tant que sous-produits

The diazo group of a series of α-diazo carbonyl compounds can be reduced to the corresponding CH2 group by Bu3SnH under Cu(acac)2-catalytic or photochemical conditions. The mechanistic aspects of this reaction were investigated in some detail, and a possible reaction pathway was discussed.

Structural optimization and preliminary structure-activity relationship studies of a series of N-substituted maleimide fused-pyrazole analogues with Cdc25B inhibitory activity, starting from a high-throughput screening hit, are illustrated. A simplified 3,5-diacyl pyrazole analogue was obtained as the most potent compound (118, IC50 = 0.12 mu M) with a 270-fold increase in potency. (C) 2010 Elsevier Ltd. All rights reserved.
