摘要:
Synthesis of a novel heterocycle comprising N-methylmorpholine, spiroindandione and indenone units in good yield via one-pot pseudo four-component cascade cycloaddition reaction is described. The structure of the cycloadduct was elucidated by spectroscopic analysis and its complete stereochemistry was assigned by single crystal X-ray diffraction analysis. Further, the mechanistic rationalization for the formation of the hitherto unexpected cycloadduct is provided by performing density functional theory (DFT) calculations. (C) 2014 Elsevier B.V.
