Efficient microwave assisted syntheses of 2,5-diketopiperazines in aqueous media.
Aqueous in situ one-pot N-Boc-deprotection-cyclization of N alpha-Boc-dipeptidyl-tert-butyl and methyl esters under microwave irradiation afforded 2,5-diketopiperazines (DKPs) in excellent yields. This protocol is rapid, safe, environmentally friendly, and highly efficient, and showed that the tert-butoxy moiety is also an excellent leaving group for these cyclizations.
متن کاملMicrowave-Assisted Hydrogenation of Codeine in Aqueous Media
An efficient one-pot microwave-assisted hydrogenation of codeine was achieved in aqueous solution. This technique is simple, fast, environmentally friendly, and highly efficient. Structure of produced dihydrocodeine was approved by using FT-IR, (1)H NMR, (13)C NMR, EIMS, and elemental analysis technique. Its purity analysis was performed by using HPLC and assay analysis was performed by using p...

متن کاملUse of Microwave-Assisted Oxidation for Removal of the Pesticide Chlorpyrifos from Aqueous Media
-The use of pesticides in agriculture has contributed to a massive increase in global food production. But the adverse impact of pesticides on living organisms has led to a growing concern about residues in soils and in aqueous media. Advanced oxidation processes (AOPs) have proven particularly useful in degrading toxic organic compounds found in wastewater to less toxic reaction products or ul...
متن کاملAqueous microwave-assisted cross-coupling reactions applied to unprotected nucleosides
Metal catalyzed cross-coupling reactions have been the preferred tools to access to modified nucleosides (on the C5-position of pyrimidines and on the C7- or C8-positions of purines). Our objective is to focus this mini-review on the Suzuki-Miyaura and on the Heck cross-couplings of nucleosides using microwave irradiations which is an alternative technology compatible with green chemistry and s...
