Small molecules that accomplish the same result would provide a powerful complement to the genetic approach, but it generally is believed that such molecules are rare. There are several natural products, however, that illustrate the feasibility of this approach. Split-pool synthesis now provides a ...

The sensitivity analysis and the validity of the results itself are in accordance with in situ testing undertaken in that area for mussel nests.The Canadian Geographer / Le Géographe canadienJEAN-MARIE M. DUBOISMOHAMED HABBANE
The main fragmentation is directed by the allylic position of the alcohol function. Deuterium labeling and the presence of a methyl substituent in different positions suggest that some degradations occur through a cyclic structure of the molecular ion. The Cope rearrangement, a normal thermal reaction...
Using the same conditions, the acetylation of methoxy derivatives of these amides and nitriles gave rapidly and in high yields, the corresponding ortho and para derivative with or without demethylation.Jean-Pierre BacheletJean-Marc ClavelPierre DemersemanRené Royer...
