Allelopathy is a natural and eco-friendly process causes agricultural plants to generate phytotoxins called "allelochemicals" that hinder or promote growth. The chemical substances generated through allelopathy can be potential tool to control agricultural important pests. Allelopathy can replace agrochemicals for crop disease and pest management. Agrochemical used in agriculture pollute the environment, lowers food quality, and increases disease-resistant biotypes. An agronomist can collaborate with a molecular scientist or plant breeder to selectively boost disease suppression by understanding allelopathy's physiological foundation. Allelochemicals are natural pesticides that fight disease, weeds, and insects, according to experts. Disease management strategies have been redesigned recently. Frequently, structural modifications or the synthesis of chemical analogs increase their bioactivity. Even though the progress in this regard is sluggish, some encouraging results are emerging, and many more are anticipated in the near future. This review attempts to discuss these characteristics of allelopathy for the rational management of diseases.

Allelopathy may be a current ecological advance of interference between organisms that will use for handling unwanted plants, insect pests, and diseases in plants. In many crops, allelopathy are often used resulting crop rotation, victimization cover crops, mulching, crop dyspnoeal and plant extracts for ordinary insect pest management. Plant pathogens together with fungi, bacteria, viruses, and nematodes are responsible for great yield losses in several economically vital crops. Use of artificial agrochemicals as soil covering, foliar spray or seed dressing is that the preferred approach for the management of crop diseases in recent days. However, due to the adverse effects of those chemicals on health and environment, customers are presently tightened turn out, that is freed from these chemicals. Natural compounds derived from plants are a lot of environmentally safe than artificial chemicals. Several recent studies have shown that allelochemicals will effectively be used for the management of various plant pathogens. Allelopathy so offers a lovely environmentally friendly different to pesticides in agricultural pest management. Their biopotency is often increased by structural changes or the synthesis of chemical analogs supported them. Though the progress during this regard is slow, even so some promising results are returning and a lot of are expected within the future. This review makes an attempt to discuss these characteristics of allelopathy for the justifiable management of pests.

“…The bulk of the study focuses on the structures of aryl acetamide-derived enolates and their alkylation . Although this is logical given the prevalence of pharmaceutical agents with aryl propionate substructures and considerable room for further development of their syntheses using the Oppolzer enolates, the aryl acetamide-derived enolates are more structurally tractable than their alkyl counterparts. For the casual readers, the Discussion summarizes the solvent-dependent structures and mechanism of alkylation.…”

Lithiated Oppolzer Enolates: Solution Structures, Mechanism of Alkylation, and Origin of Stereoselectivity

Camphorsultam-based lithium enolates referred to colloquially as Oppolzer enolates are examined spectroscopically, crystallographically, kinetically, and computationally to ascertain the mechanism of alkylation and the origin of the stereoselectivity. Solvent-and substrate-dependent structures include tetramers for alkyl-substituted enolates in toluene, unsymmetric dimers for arylsubstituted enolates in toluene, substrate-independent symmetric dimers in THF and THF/toluene mixtures, HMPA-bridged trisolvated dimers at low HMPA concentrations, and disolvated monomers for the aryl-substituted enolates at elevated HMPA concentrations. Extensive analyses of the stereochemistry of aggregation are included. Rate studies for reaction with allyl bromide implicate an HMPA-solvated ion pair with a + Li(HMPA) 4 counterion. Dependencies on toluene and THF are attributed to exclusively secondary-shell (medium) effects. Aided by density functional theory (DFT) computations, a stereochemical model is presented in which neither chelates nor the lithium gegenion serves roles. The stereoselectivity stems from the chirality within the sultam ring and not the camphor skeletal core.
