, p. 6927 - 6930 (2004)
The synthesis and chemical reactivity of pyridazinedione-based enediynes (1, 2) are described. Both of these enediynes, namely the dihydro compound 1 and its corresponding tetrahydro analogue 2, were prepared by double N,O-alkylation of the corresponding
Synthesis and reactivity of enediyne-nucleobase hybrids: Effect of intramolecular π-stacking

Three distinct classes of nucleobase-containing enediynes 1-9 with varying nature of the linker have been synthesized to explore the effect of π-stacking interaction in accelerating the rate of Bergman cyclization (BC). Chemical reactivity study, both experimental and computations demonstrated the important role that aromatic π-stacking interactions between the appended nucleobases within an enediyne frame play in lowering the activation barrier of Bergman cyclization.
Photoisomerization as a trigger for Bergman cyclization: Synthesis and reactivity of azoenediynes
Kar, Moumita,Basak, Amit,Bhattacharjee, Manish
, p. 5392 - 5396 (2007/10/03)
Cyclic enediynes 1a and 2a containing stable E-azo moiety (azoenediynes) have been synthesized. These compounds upon irradiation with long wavelength UV isomerize to the Z-compounds 1b and 2b, which can be thermally reisomerized to the Z compounds. Reacti
