PdII-Catalyzed Cyclization of 1-Cyclopropyl-2-propynyl Acetates

open access: yesCHIMIA, 1985
PdCl2(MeCN)2 catalyzes the cyclization of 1-cyclopropyl-2-propynyl acetates to 3-methyl-1,4-cyclopentadienyl acetates, which are cleaved in situ to 2-cyclopentenones.

Apples as enantiospecific bioreagents in the hydrolysis of racemic esters and oxygenation of alcohols obtained during the process

open access: yesActa Societatis Botanicorum Poloniae, 2014
Biotransformation carried out by apples (Malus silvestris) resulted in enantiospecific hydrolysis of racemic acetates, the derivatives of secondary aromatic-aliphatic or terpenic alcohols. The alcohols are oxygenated to ketones (reversible reaction). The

An environmentally benign cascade reaction of 1,2,3-indantriones with ethyl 2-(pyridine-2-yl)acetates for site-selective synthesis of 5H-isochromeno[4,3-b]indolizin-5-ones

open access: yesGreen Synthesis and Catalysis, 2021
A novel approach was developed for the synthesis of 5H-isochromeno [4,3-b]indolizin-5-ones (ICIDOs) 3 through a cascade reaction of 1,2,3-indantriones 1 with ethyl 2-(pyridine-2-yl)acetates 2.
