标题:钯在温和条件下对碳-二乙胺介导的苯酚衍生物的加氢脱氧作用
摘要:我们发现,在二乙胺存在下,在pd / C催化的氢化条件下,酚羟基很容易通过芳基磺酸盐脱氧,该方法也可用于吗啡的加氢脱氧,得到3-Deoxy-7,8-Dihydromorphine .二乙胺不仅是在反应过程中产生的相应甲磺酸衍生物的清除剂,而且还是pd / C催化的芳基磺酸盐还原的强促进剂.该催化剂体系由于其温和的反应条件,易于处理并且不需要特定的设备,因此可以为各种酚衍生物的脱氧提供通用的方法.

标 题 :Compositions for chemical synthesis of peptides
发明人：SEIFERT COLE
权利人:SEDERMA SA
摘要:The disclosure relates to compositions that can serve as anchors for the chemical synthesis of peptides. Anchor molecules can include GAP constituents, linker constituents, amino acid constituents, and/or stopper constituents. Anchor molecules can also include anchor peptides, wherein an anchor peptide can be removably coupled with an amino acid of a given sequence and act as a GAP anchor by achieving solubility control over the target peptide as it is synthesized via the addition of one or more other amino acids: the anchor peptide can then be removed from the target peptide. A novel method of peptide synthesis that utilizes novel anchor molecules and/or anchor peptides is also presented.

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.
