An efficient, facile and environmentally benign synthesis of a library of 1,2,3-triazolyl chalcone hybrids (3a-u) has been accomplished by grinding the reactants at room temperature in excellent yields in very short reaction time. Subsequently, SbCl3 catalysed Michael addition of indoles to the chalcones afford 1,2,3-triazolyl indole hybrids (5a-l) in excellent yields.

An efficient and facile synthesis of divergent C-3/C-5 bis-functionalized 2-oxindoles from 5-formyl-Morita-Baylis-Hillman adducts of oxindole
Kodirajan Selvakumar Kandapalam Arun Prasath Lingam Rama Varma Luxmi Varma Poovan Shanmugavelan
An efficient and facile synthesis of divergent C-3/C-5 bis-functionalized 2-oxindole derivatives has been achieved from 3,5-bis-Morita-Baylis-Hillman (MBH) adducts of oxindole via nucleophilic substitution reaction for the first time. Wider scope of substrate and rate acceleration has been observed in second MBH reaction under typical reaction condition. The synthetic usefulness of bi-functionalized bis-allyl derivative has been demonstrated by the synthesis of potent bis-pyrazole via [3+2]-annulation strategy.
