Synthesis of furan-2,3,4-tricarboxylate in biphasic water–Et2O solvent system
摘要:
The reaction of dialkyl acetylenedicarboxylates with ethyl bromopyruvate or alpha-chlorocarbonyl compounds in the presence of 1,4-diazabicyclo[2.2.2]octane led to furan-2,3,4-tricarboxylates or the related 2-acetylfuran-3,4-dicarboxylates in excellent yield.

acetylenes with isomünchnones is presented as a general methodology for the combinatorial formation of a furan based library. Additionally, through the development of a novelthermolytic cleavage step, this furan synthesis yields pure product from the solid-phase in a temperature dependent manner.

The generation and cycloaddition reactions of polymer-supported mesoionic isomünchnones derived from α-diazocarbonyl intermediates is described in this report. This chemistry provides a method for preparing combinatorial bibraries of functionalized furans and features cycloreversion as a new synthetic strategy for “traceless” synthesis of small organic molecules.

A new and convenient cyclization method for the synthesis of polysubstituted furans in a single-step via ammonium ylide routes was reported. In this process, dimethyl acetylenedicarboxylate reacted with ammonium ylide to produce polysubstituted furan in the presence of anhydrous K2CO3 at room temperature. It is very economical, environmentally friendly and very easy to carry out.
