COMMUNICATION
Journal Name
usefulness of the method has been demonstrated by de-silylation
and its transformation into various functionalised chromones. The
alkynylation of acyclic enamines reported herein should be of
particular importance because one can access several other
heterocyclic scaffolds using this chemistry.
Generous financial support by the Department of Science and
Technology (DST), New Delhi (grant number SB/S1/OC-17/2013)and
the Council of Scientific and Industrial Research (CSIR), New Delhi
(grant number CSC0108 and CSC0130) is gratefully acknowledged.
We thank Dr. Rahul Banerjee for assistance with X-ray
crystallography. M. O. A. thanks CSIR for the award of Junior
Research Fellowship.
