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.

发明人：HENDRICKSON JAMES B; RODRIGUEZ CESAR
权利人:HENDRICKSON JAMES B; RODRIGUEZ CESAR
摘要:A method for the synthesis of particular isoquinoline compounds which are useful intermediates in the preparation of members of the family of opium alkaloids, such as morphine and codeine. Steps in the process include the acylation of the isoquinoline nitrogen; reaction of the acylated isoquinoline with a phosphorous compound; and condensation with a benzaldehyde derivative to yield a 1-benzyl isoquinoline.

摘要:The present invention discusses a novel process for the synthesis of [R-(R*,R*)]-2-(4-fluorophenyl)-B,D-dihydroxy-5-(1-methylethyl)-3-phenyl-4-[(phenylamino)carbonyl]-1H-pyrrole-1-heptanoic acid hemi calcium salt by using 4-fluoro-α-[2-methyl-1-oxopropyl]η-oxo-N-β-diphenylbenzene butaneamide with (4R)-methyl 6-(2-aminoethyl)-2,2-dimethyl-1,3-dioxane-3-acetate. The compound so prepared is useful as inhibitors of the enzyme HMG-CoA reductase and are thus used as hypolipidemic and hypocholesterolemic agents.
