An efficient synthesis of ethyl α-amino-β, β-diethoxypropionate (1), via a titanium
tetrachloride-catalyzed coupling reaction of ethyl nitroacetate and triethyl orthoformate, is …

The α-Chloro-α-acetoxy-β-keto-esters were prepared from β-keto-esters in good overall
yields. These compounds reacted as α, β-diketo-ester equivalents with amidrazones …

α-Nitro ketones can be transformed selectively into trialkyl-substituted pyrazines via reaction
with α-amino ketones using octyl viologen as an electron-transfer reagent. The new …

The three-component reactions of 4-dimethylamino-or 4-methoxypyridine with
acetylenedicarboxylates and arylidene cyanoacetates showed very interesting molecular …

Abstract Reaction between 5-cyano-3, 6-di (het) aryl-1, 2, 4-triazines and arylhydrazines
with the following aza-Diels–Alder autoclave reaction affords hardly available 2-amino-3, 6 …

In this report, we review the C-and N-functionalization of the pyridazine nucleus via
palladium-catalyzed reactions (Suzuki, Stille, Sonogashira, carbonylation, Heck, Buchwald …

A Cu (I)-promoted exclusive synthesis of pyrrolo [2, 1-a] isoquinoline derivatives involving
(E)-2-methoxyethene-1-sulfonyl fluoride (MESF) and isoquinolinium N-ylides is described …

Symmetrical trichlorotriazine derivatives such as 2, 4, 6-trichloro-1, 3, 5-triazine and
trichloroisocyanuric acid were explored as Vilsmeier–Haack type reagents in the presence …

A simple and efficient catalyst-free synthesis of pyrrolo [1, 2-a] quinoline derivatives from 2-
methylquinolines, aldehydes, and alkynoates via dehydration/[3+ 2] cycloaddition has been …
