Kinetics of 1-hexanol etherification on Amberlyst 70 [PDF]
The kinetics of the liquid-phase etherification of 1-hexanol to di-n-ethyl ether and water on the ion-exchange resin Amberlyst 70 in the temperature range 423-463 K is studied. The strong inhibition effect of water is considered following two approaches.

Total Syntheses of HMP-Y1, Hibarimicinone, and HMP-P1 [PDF]
Total syntheses of HMP-Y1, atrop-HMP-Y1, hibarimicinone, atrop-hibarimicinone, and HMP-P1 are described using a two-directional synthesis strategy. A novel benzyl fluoride Michael–Claisen reaction sequence was developed to construct the complete carbon ...

Copper‐Catalyzed Three‐Component Selective 1,4‐Amino Oxygenation of 1,3‐Dienes
Enclosed is a copper‐catalyzed selective 1,4‐amino oxgenation of 1,3‐dienes with the presence of a strong Brønsted acid. This three‐component transformation offers a novel and powerful approach to construct (E)‐1,4‐allylic amino oxygenated motifs by the simultaneous installation of structurally diverse alkylamines and alcohols directly onto 1,3‐dienes.

Dehydration of n-propanol and methanol to produce etherified fuel additives
An ether is an organic compound that consists of an oxygen atom bonded to two alkyl or aryl groups. In this work, we investigate the bimolecular dehydration of two alcohols, n-propanol and methanol with catalysts that are used in transesterification ...

Iodine-Catalyzed Etherification of Morroniside
In this study, we describe a highly selective etherification procedure of unprotected morroniside catalyzed by molecular iodine in acetone. The etherification reaction furnished 7-O-alkyl ether derivatives in reasonable yields within few hours under neutral conditions.
