摘要:已经发现,在存在或不存在溶剂的情况下,在硅胶上的oxone或在某些情况下在氧化铝上可将伯胺和仲胺3选择性氧化为相应的羟胺4.在后一条件下处理boc保护的l-赖氨酸(6),得到羟胺7,产率极高.选择性不成问题的三烷基胺1A和吡啶(1B)可以通过oxone在硅胶或氧化铝上以及(ch(3))(3)cooh在硅胶上容易氧化为相应的氧化物2 .微波辐照辅助的无溶剂氧化更具强迫性,同时仍然选择性地提供羟胺4,是选择的合成方法.讨论了这些反应的机理.

摘要:The present invention is directed to compositions and methods for enhancing synthesis of nucleic acid molecules, particularly GC-rich nucleic acid molecules. Specifically, the invention provides compositions comprising one or more nitrogen-containing organic compounds having a formula selected from the group consisting of formula I and formula II (or salts or derivatives thereof), preferably 4-methylmorpholine N-oxide or betaine (carboxymethyltrimethylammonium), and further comprising one or more compounds selected from the group consisting of proline and an N-alkylimidazole compound, and more preferably proline, 1-methylimidazole or 4-methylimidazole. The invention further relates to methods for enhanced, high-fidelity synthesis of nucleic acid molecules, including via amplification (particularly PCR), reverse transcription, and sequencing methods. The invention also relates to nucleic acid molecules synthesized by these methods, to fragments or derivatives thereof, and to vectors and host cells comprising such nucleic acid molecules, fragments, or derivatives. The invention also relates to kits for synthesizing, amplifying, reverse transcribing or sequencing nucleic acid molecules comprising one or more of the compositions of the invention.
