Isolation, structural determination and anti-hyperglycemic effect of dietthyl terephthalate extracted from the leaves of Dalium guineense (Caesalpiniaceae)
(2023)
Previous work had demonstrated the lack of hypoglycemic effect of the butanol-ethyl acetate fraction (BEAF) of
the leaves of Dialium Guineense (Caesalpiniaceae). However, this same fraction is anti-hyperglycemic in ...

Enantioselective acces to five- and six- membered nitogen - containing heterocycles, based on the asymetric Michael addition of chiral imines and chiral enamino esters.
(1998)
The addition reaction of chiral imines, (ent-10, 48, 70) and chiral enamino esters (52, 55, 73) with maleic anhydride (32), citraconic anhydride (57), a-chloroacrylonitrile (29), and nitroethylene (74), has been investigated. ...
Synthesis of N-Substituted piperidines from piperidone
(2015)
A reductive amination reaction between N-boc-piperidin-4-one and 3,4-dichloroaniline was successfully
employed for the synthesis of the N-(3,4-dichloropheny)-N-(2-phenoxylethyl) piperidin-4-amine. The synthesis of a
small ...
