摘要:研究了磷化钠r 2 Pna和其他碱金属磷化物r 2 Pm(m = Li和k)的制备,应用和反应机理.R 2 Pna可以通过sd(精细分散在矿物油中的钠)与次膦酸酯r 2 Por'和氯膦r 2 Pc1的反应准确而选择性地制备.R 2 Pna也可以通过选择性裂解c-p键由三芳基膦和二芳基膦制备.在这些反应中,Na优于li和k.R 2 Pna与多种arcl反应以有效产生r 2Par.Arcl优于arbr和ari,因为它们只会降低产品收率.另外,Ph 2 Pna优于ph 2 Pli和ph 2 Pk,因为ph 2 Pli不产生与phcl的偶联产物,而ph 2 Pk仅产生低产率的产物.Arcl苯环上的吸电子基团极大地促进了与r 2 Pna的反应,而烷基降低了反应活性.氯乙烯和烷基氯rc1也有效地反应.当t-Bucl没有产生相应的产物,金刚烷基卤化物可以高产率得到相应的膦.通过这种方法,由相应的氯化物制备了多种膦.还可以方便地从ph

摘要:A reagent for organic synthesis with which a chemical reaction can be conducted in a liquid phase and unnecessary compound(s) can be easily separated at low cost from the liquid phase after completion of the reaction. The reagent for organic synthesis reversibly changes from a liquid-phase state to a solid-phase state with changes in solution composition and/or solution temperature, and is for use in organic synthesis reactions. This reagent for organic syntheses facilitates process development. With the reagent, research on and development of, e.g., medicines through, e.g., compound library synthesis, etc. can be accelerated. It can hence contribute to technical innovations in the biochemical industry and chemical industry.

权利人:UNIV TEXAS TECH SYSTEM
摘要:Disclosed is a system and method for Fmoc/tBu solution-phase peptide synthesis including the development of a new benzyl-type GAP protecting group, and related uses thereto. This novel GAP protecting group is utilized in place of a polymer support, facilitating C to N Fmoc peptide synthesis without chromatography, recrystallization, or polymer supports. The GAP group can be added and removed in high yield.
