Gram-scale reactions
WebJan 29, 2024 · The microdroplet/thin film reaction yield improved on recycling from 33% to 86% and from 32% to 72% for the Katritzky and Suzuki coupling reactions, respectively. The Claisen-Schmidt reaction was chosen to test the capability of this system in gram scale syntheses and rates of 3.18 g per h and an isolated yield of 87% were achieved. Web1 day ago · The synthetic utility of this strategy is further exhibited by the gram‐scale synthesis and late‐stage functionalization. By slightly tunning the reaction conditions, the alcohols (1°, 2° and 3°) can be afforded from phenol derivatives, which is a good strategy for the deprotection of para ‐methoxyphenyl (PMP) group to recover the ...
