The synthesis, spectroscopy and fungicidal activity of phosphoric acid amides Author: Mavrommatis, Christakis NikouAuthor: Christakis Nikou Mavrommatis. IJRRAS 12 (1) July Adelowo Synthesis, Characterization & Fungicidal Activity and Peronospora tabacina. The in-vitro testing of the synthesized compounds for their fungicidal activity was carried out in Microbiology laboratory. The inhibition of germinated spores was assessed by . might enhance the fungicidal activities of pyrazole analogues, 32 novel substituted pyrazole derivatives were designed and synthesized in this paper, and the fungicidal activities of these compounds were tested. The structure-activity relationships were also examined. 2. Result and Discussion Chemical Synthesis. The previous discoveries of butyl fenbufen amide analogs with antitumor effects were further examined. The amide analogs with 1, 3, 4 and 8 carbons chains were prepared in % yield. Fenbufen had no cytotoxic effects at concentrations ranging from 10 to μM. Methyl fenbufen amide had significant cytotoxic effects at a concentration of μM. As the length of the alkyl amide side chain Cited by: 7.

Fungicidal Activity; Sulphide Derivatives; Synthesis. 1. INTRODUCTION. Variations in the structure of sulphur-containing com-pounds have led to increased fungicidal activity [1,2]. Fungicides are chemicals that combat the attack of vari-ous fungi species. Organosulphur compounds are eco-nomically important fungicides that play a significantFile Size: KB. Synthesis of the fungicidally active quinolinyloxy acetamides 9 and The methyl es which is a key intermediate in the synthesis of the fungicidally active am is perfectly suited for the transformation into derivatives with a different quinoline substitution pattern by exchange of the bromine by: Newer Methods of Preparative Organic Chemistry, Volume III focuses on the improved methods in preparative organic chemistry. This book presents a variety of topics, including the synthesis of acetylenes, methods for the preparation of pyrylium salts, and the use of phosphoric acid chlorides in the preparation of esters of phosphoric acids. Triesters of phosphoric acid OP(OR)3 (R = Me, Et, n-Bu, SiMe3) react with [M(NMe2)3]2 (M = Al (1), Ga (2)) in nonaqueous aprotic solvents with the formation of amorphous alumino- and gallophosphates MPO4 (M = Al, Ga). Triphenyl phosphate, on the other hand, undergoes ligand scrambling with 1 and 2. Aluminophosphate also results from the reaction of AlCl3 with OP(OSiMe3)3. The products and Cited by:

A new type of highly dispersible phosphoric acid functionalized carbon based nanocatalysts was prepared in a simple synthetic procedure. The catalytic activity of developed catalyst was evaluated toward the synthesis of pyrano[2,3-c]pyrazoles in one-pot, four-component reaction of hydrazines, malononitrile, ethyl acetoacetate and aldehydes in water. The reaction afforded pyrazoles with Cited by: AlPO4 and GaPO4 are formed in the reaction of phosphoric acid triesters OP(OR)3 (R = Me, Et, n-Bu, SiMe3) with aluminium and gallium amides [M(NMe2)3]2 (M = Al (1), Ga (2)), respectively, in nonaqueous solvents. The model for the initial step in these reactions is an adduct (Me2N Cited by: Thirteen decades of peptide synthesis: key developments in solid phase peptide synthesis and amide bond formation utilized in peptide ligation. Amino Acids , 50 (1), Cited by: A new enantioselective total synthesis of phlegmarine-type Lycopodium alkaloid lycoposerramine-Z (1) has been accomplished, using one-pot chemoselective sequential additions of two different Grignard reagents to the bis-Weinreb-amide intermediate and an efficient construction of the fully fuctionalized cyclohexanone intermediate with a chiral phosphoric acid catalyzed enantioselective Cited by:
