Convergent Synthesis of Menaquinone‐7 (MK-7)
A practical synthesis of menaquinone-7 (MK-7, vitamin K2) in the all-trans form was designed. Stereoselective synthesis of MK-7 was achieved through a “1 + 6” convergent strategy by condensation of two building blocks, menadione monoprenyl derivative (fragment “1”) with hexaprenyl bromide (fragment “6”, 82%). Pd-catalyzed desulfonation with LiEt3BH (78%) was followed by oxidation of the hydroqu...
متن کاملSafer one-pot synthesis of the 'SHAPE' reagent 1-methyl-7-nitroisatoic anhydride (1m7).
Estimating the reactivity of 2'-hydroxyl groups along an RNA chain of interest aids in the modeling of the folded RNA structure; flexible loops tend to be reactive, whereas duplex regions are generally not. Among the most useful reagents for probing 2'-hydroxyl reactivity is 1-methyl-7-nitroisatoic anhydride (1m7), but the absence of a reliable, inexpensive source has prevented widespread adopt...

JALDA, therefore, would like to show inclination towards the view that the reality of the world is not a fixed entity standing out there to be measured by our pre-fabricated ‘scientific’ instruments. In line with Haghshenas’ argumentation, not only can theories and instruments shrink to ornamental entities but also they can turn into what Karl Popper calls pseudo-science, knowledge of an ‘ideol...

Business-to-Business integration (B2Bi) is considered to be not merely an IT-issue, but also a business problem. This paper draws attention to the challenges companies within an Extended Enterprise are confronted with when integrating their systems. We primarily pay attention to coordination problems that may arise. To overcome these problems we propose the use of Enterprise Architecture descri...
