The chemistry of heterocyclic compounds has traditionally been and remains a bright area of
chemical science in Russia. This is due to the fact that many heterocycles find the widest …

Monoterpenes derived from various biomass constitute an important platform for
synthesizing fragrances, intermediates, and pharmaceuticals. In this review, the most recent …

The use of clay minerals as catalyst is renowned since ancient times. Among the different
clays used for catalytic purposes, halloysite nanotubes (HNTs) represent valuable resources …

Abstract A number of SO 3 H-functionalized solids (biochar, montmorillonites, carbon and
halloysite nanotubes) has been studied as catalysts in the cascade Prins-Ritter reaction of …

Halloysite nanotubes can be used for the preparation of solid catalysts. Owing to their
natural availability at low-cost as well as to their large and easy-to-functionalize surface, they …

Isopulegol, a pool of abundant chiral terpene, has long served as the starting material for the
total synthesis of isopulegol‐based drugs. As an inexpensive and versatile starting material …

Hierarchical Beta zeolites obtained from concentrated reaction mixtures (H2O/Si= 2.5–7.0)
in the presence of CTAB and their conventional and nanosponge analogues were …

Several hierarchical beta zeolites prepared via hydrothermal treatment of a concentrated
zeolite gel-precursor were investigated in Prins cyclisation between (–)-isopulegol and …

Abstract Condensation of (−)-isopulegol with acetone was investigated at 25–40° C over
clay based materials (K10, cloisite Na+ and halloysite nanotubes) modified with sulfonic …

Synthesis of Beta zeolite catalysts was carried out using two different methods. The
influence of such parameters as synthesis time and temperature, gel composition and gel …
