标题:有序降解:两种大分子概念的简单而多功能的一锅组合,以编码多样化且空间调节的降解性函数
摘要:开环聚合(rop)和逐步增长聚合(sgp)这两种大分子概念的巧妙一锅组合被证明是一种简单而强大的工具,可以设计具有多样化和空间性的序列控制聚合物库.调节的降解功能.当有机催化条件从碱性切换到酸性时,Rop 和 Sgp 在室温下依次发生,并且各自允许编码特定的可降解键. Rop 控制降解功能的序列长度和位置,而互补乙烯基醚和羟基链端之间的 Sgp 能够形成缩醛键和高摩尔质量共聚物.结果是同一大分子内容易发生本体或表面侵蚀的可裂解键的合理组合.该策略用途广泛,与目前的脂肪族聚酯或聚碳酸酯相比,具有更高的化学多样性和对一级结构的控制水平,同时简单,有效,原子经济,并具有可扩展性的潜力.

标题 :Bio-intermediates for use in the chemical synthesis of polyketides
发明人：SANTI DANIEL; ASHLEY GARY; MYLES DAVID C
摘要:The present invention relates to compounds made by a subset of modules from one or more polyketide synthase (“PKSâ€?) genes that are used as starting material in the chemical synthesis of novel molecules, particularly naturally occurring polyketides or derivatives thereof. The biologically derived intermediates (“bio-intermediatesâ€?) generally represent particularly difficult compounds to synthesize using traditional chemical approaches due to one or more stereocenters. In one aspect of the invention, an intermediate in the synthesis of epothilone is provided that feeds into the synthetic protocol of Danishefsky and co-workers. In another aspect of the invention, intermediates in the synthesis of discodermolide are provided that feed into the synthetic protocol of Smith and co-workers. By taking advantage of the inherent stereochemical specificity of biological processes, the syntheses of key intermediates and thus the overall syntheses of compounds like epothilone and discodermolide are greaty simplified.

摘要:The invention relates to commercially viable process for the synthesis of key intermediates for the preparation of statins, in particular Rosuvastatin and Pitavastatin or respective pharmaceutically acceptable salts thereof. A new simple and short synthetic route for key intermediates is presented which benefits from the use of cheap and readily available starting materials, by which the conventionally most frequently used DIBAL-H as reducing agent can be avoided.
