2-呋喃甲酰肼 | 2-furoic acid hydrazide | 3326-71-4 | C5H6N2O2 | 126.115 |
The adduct produced in the reaction between alkyl isocyanides and dialkyl acetylenedicarboxylates was trapped by furan-2-carboxylic acid arylidene-hydrazides to afford highly functionalised ketenimines in good yields. The reaction is characterised by mild conditions, high selectivity, and tolerance to various functional groups.
The characteristic feature of many commercial agrochemicals and drugs is the 5-nitro-2-furyl or 2,5-dimethyl-3-furyl building block. Within the scope of our research aimed at utilization of dipolar cycloaddition reactions to prepare new compounds with potential biological and phytoeffectorial activity, we report on the synthesis of some substituted hydrazones
