Direct esterification of succinic acid with phenol using zeolite beta catalyst
Le, Son Dinh,Nishimura, Shun,Ebitani, Kohki
, p. 20 - 23 (2019/01/16)
Direct esterification of succinic acid with phenol in the presence of zeolite catalysts was explored. H+-zeolite β (SiO2/Al2O3 = 150) has emerged as the most effective solid acid catalyst, affording 96% yield of
A Two-Directional Synthesis of (+)-β-Isosparteine
Al-Saffar, Firas M.,Brown, Richard C. D.
, p. 3502 - 3504 (2017/07/15)
A two-directional synthesis of (+)-β-isosparteine is described in five steps from glutaric acid, where the entire carbon and nitrogen backbone of the alkaloid, possessing the requisite relative and absolute stereochemistry at its four stereogenic centers, is assembled using a double imino-aldol reaction.

experimental part, p. 921 - 931 (2012/02/01)
Esterification of several types of mono-and disubstituted phenols with various mono-and dialkanoyl chlorides was performed in phase-transfer catalysis conditions, using tetrabutylammonium chloride in a mixture of aqueous NaOH and dichloromethane. The process is particularly efficient (almost quantitative yields) as well as rapid (only 5 min reaction time, at a temperature of0°C). Taylor & Francis Group, LLC.
