Due to its inherent advantages such as easy recovery and reuse of the catalysts/ reagents, and environmentally friendly nature, the heterogeneous system has gain popularity in the realm of organic synthesis. In recent years, several chemically or biologically potent molecules are achieved through heterogeneous synthesis strategies. By recalling some of the classical fundamentals of the heterogeneous system in important organic synthesis, this mini-review outlines the recent developments in the applications heterogeneous catalysts and reagents; particularly in the solid phase synthesis, esterification and transesterification reactions to produce biodiesel, and Henry reaction.

One of the organocatalysts 1,4-diazabicyclo[2.2.2]octane (DABCO) is an excellent solid catalyst in a number of reactions. It is also a good nucleophile and a base in numerous reactions for the synthesis of heterocycles. DABCO catalyzes many reactions like cycloaddition reactions, coupling reactions, Baylis-Hillman reaction, Henry reaction, ring opening reactions, etc. One more advanced feature of these reactions is that they proceed through environmental friendly pathway. DABCO has more advantages than other organic catalysts because it is an inexpensive, non.toxic base, an ecofriendly and a highly reactive catalyst for building of organic frameworks, which produce the desired products in excellent yields with high selectivity. Many catalytic applications of DABCO have been reported for the synthesis of an organic framework which has been discussed in this review.

: Henry reaction is an important reaction employing carbonyls which furnishes β-nitro alcohol, nitroalkene, α-nitro ketones, β-amino alcohol as products and byproducts that may be transfigured as building blocks for other synthetic reactions. This paper focuses on various synthetic routes for Henry reaction, a versatile reaction of high significance in organic synthesis. The paper discusses the chemistry and plausible products of the reaction, along with the various available synthetic routes for the same, ranging from classical conventional methods to modern methods of green chemistry trends. Use of various catalysts as rate enhancer as well as use of various catalysts as enantioselective frontman for stereoselective reactions, have been described in this work.
