A series of highly hindered N1,N2N2,N3,N3-penta-alkylguanidines has been synthesised from inexpensive starting materials; these strongbases show interesting effects in organicsynthesis.
已经从廉价的起始原料合成了一系列高度受阻的N 1,N 2 N 2,N 3,N 3-戊烷基胍。这些强碱在有机合成中显示出有趣的作用。
Highly efficient esterification of carboxylic acids with O–H nucleophiles through acid/iodide cooperative catalysis
The esterification of carboxylicacids is an important reaction for preparing esters which find wide applications in various research fields. In this manuscript, we report an acid/iodide cooperative catalytic method which enables highly efficientesterification of carboxylicacids with a wide range of equivalent O–H nucleophiles including both alcohols and weak nucleophilic phenols. Under the reaction
