Dihydro-oxadiazine and its derivatives have been demonstrated to be important heterocyclic
scaffold platform with bioactive diversity, which present wide activities such as …

Aniline derivatives were diazotized and coupled with 3-aminocrotononitrile to give the
corresponding 2-arylhydrazono-3-ketiminobutyronitriles. Cyclization of these arylhydrazono …

Time, energy, and cost saving; waste reduction; health and safety preservation represent

Abstract Three carboxylated cyanine dyes, 2-[(1-butyl-3, 3-dimethyl-5-carboxylindoline-2-
ylidene) propenyl]-[1-butyl-3, 3-dimethyl-7-(1-ethyl-1 H-1, 2, 3-triazole-4-yl]-1 H-benz [e] …

A series of novel polyfunctionalized acyclic and heterocyclic dye precursors and their
respective azo (hydrazone) counterpart dyes and dye precursors based on conjugate …

An enantioselective [2+ 4]-annulation of γ-substituted allenoates with N-acyldiazenes has
been developed for the first time. In the presence of an L-proline-derived DMAP analogue …

Cyanoacetylhydrazine reacted with the ω-bromoacetophenones 2a, b to give hydrazide-
hydrazone derivatives 3a, b. The latter products were cyclized to the 1, 3, 4-oxadiazine …

In this study, some novel cyanine dyes, 1, 3, and 5− 15, were synthesized by a one‐pot step
reaction of pyridinium salts 2 and/or 4 with benzenaminium salt 1. N‐{[1‐Chloro‐3, 4 …
