Three calix[4]arene-bisphosphonates were efficiently prepared in multi-step syntheses with a variable carbon chain length between the bisphosphonate and the calix[4]arene.
Even though LOC devices with the possibility to carry out multi-step syntheses have been designed, surprisingly, such systems have not been utilized for carrying out simultaneous synthesis and bio-functionalization of nanomaterials.
A scheme representing the total utilization of chemical reagents for conventional one-step and multi-step syntheses of MCM-41 are illustrated in Table 4.
During the manual inspection of the reaction corpus, it was discovered that two of the 100 CML Reactions were derived from multi-step syntheses that were described within a single paragraph.
This concept deserves more attention to bridge the gap between the "learning from nature" and "device designer" communities, as in this way the potential drawbacks of multi-step syntheses so far devised for increasing the complexity of a system might be circumvented and translation will be facilitated.
Diarylated BQs have found diverse uses as ligands,[ 8] in molecular electronics,[ 4b] natural products,[ 23] and biologically active compounds,[ 24] despite their multi-step syntheses, which are often restricted to homo-disubstituted BQs.[ 2, 25] We first explored a one-pot homo-difunctionalization (R=R′ in Scheme 1).
The following compounds were taken into the account and synthesized using a multi-step synthesis protocol.
Advanced organic lab course that introduces multi-step synthesis, NMR spectroscopy, and polymer chemistry.
The multi-step synthesis was achieved starting from trimesic acid triethyl ester.
This study describes the synthesis strategy of these potential antitumor compounds, their multi-step synthesis and their optimization.
