标 题:Solid-phase synthesis of N-alkyl amides
发明人：BROWN EDWARD G; NUSS JOHN M
权利人:CHIRON CORP
摘要:Methods for solid phase synthesis of N-alkyl amides comprise reductive amination of carbonyl compounds using a reducing agent and an amine-containing linker bound to a solid support. The methods afford high yields of linker-bound, monoalkylated amines, and subsequent coupling with acid derivatives provide derivatized N-substituted amides in excellent yields after cleavage from the solid-phase. Compositions useful in solid phase synthesis are also described.

标题 :Efficient process for the synthesis of alkoxy substituted benzaldehydes
发明人：MOHAPATRA Manoj Kumar; BENDAPUDI Ramamohanrao; MENACHERRY Paul Vincent; PAUL VINCENT
权利人:ANTHEA AROMATICS PRIVATE LTD
摘要:The present invention relates to the synthesis of alkoxy substituted benzaldehydes obtained from the corresponding alkoxy substituted benzenes. Alkoxy substituted benzaldehydes are products of broad commercial interest and are used as end products and intermediates in flavor and fragrance applications and pharmaceutical ingredients. For example, 3,4-methylendioxy-benzaldehyde (also known as heliotropin or piperonal) is used widely both as a end product and intermediate for the above mentioned applications. Other examples include 3,4-dimethoxybenzaldehyde, 3,4,5-trimethoxybenzaldehyde and 3,4-ethylenedioxybenzene which are intermediates in the synthesis of active pharmaceutical intermediates.
