摘要:Here we report a study on a reaction sequence on solid phase, suitable for the generation of molecular diversity on small heterocycles. For each reaction, suitable conditions on solid phase were worked out and a variety of reactive agents (building blocks) was utilized in an effort to grasp the system's breadth of applicability. The inventive reaction sequence can be applied, for example, to exploit by the combinatorial approaches of the split and mix concept. The reaction sequence comprises the following steps: a) a solid carrier having reactive surface groups is loaded directly or via a spacer group with a compound bearing an aldehyde or a methylketon function, b) said function is modified using the Witting reaction or the aldol condensation, c) the heterocyclic ring is closed using a compound comprising two nucleophiles, wherein at least one of the said nucleophiles is NH2.

标题 :Process for the selective addition of a compound having an activated carbon atom onto a substituted conjugated diene
发明人：MOREL DIDIER
权利人:RHONE POULENC IND
摘要:The selective addition of a compound having an activated carbon atom onto the carbon atom in the 4-position of a buta-1,3-diene carrying a hydrocarbon substituent on the carbon atom in the 2-position is achieved by reacting the compound having the activated carbon atom with the buta-1,3-diene carrying the hydrocarbon substituent in water or in an aqueous-alcoholic mixture in the presence of a catalyst which consists of at least one water-soluble phosphine and at least one rhodium compound, the catalyst being in solution in the water or aqueous alcoholic mixture. The products obtained are useful as precursors of intermediates for the synthesis of vitamins and perfumes.
