The present disclosure relates to a class of fused pyrimidine compounds of Formula I, their stereoisomers, tautomers, pharmaceutically acceptable salts, polymorphs, solvates, and hydrates thereof. The present disclosure also relates to a process of preparation of these fused pyrimidine compounds, and to pharmaceutical compositions containing them.

Intramolecular Diels-Alder reactions of ester-linked 1,3,8-nonatrienes

Penta-1,3-dienyl acrylates undergo kinetically controlled intramolecular Diels-Alder (IMDA) reactions and DFT calculations (B3LYP/6-31+G(d)) predict stereoselectivities that are in very good agreement with the experimental values. The nature of the diene

Stereoselectivity and Generality of the Palladium-Catalysed Cyclopropanation of α,β-Unsaturated Carboxylic Acids Derivatized with Oppolzer's Sultam

A series of α,β-unsaturated carboxylic acids derivatized with camphorsultam 1 a s a chiral auxiliary has been stereoselectively cyclopropanated. the selectivity of the reaction produces cyclopropanated products with the 1R,2R absolute configuration as indicated by the optical rotations as well as by an X-ray structure determineation.The temperature dependence of the reaction was studied with three substrates. the highest stereoselectivity was obtained at temperatures above 25 deg C.Branching at the α- or β-carbons disfavours complete conversion, and electron-withdrawing substituents at these positions seem to prevent the reaction.The auxiliary was removed by using titanium(IV) isopropoxide in benzyl alcohol followed by alkaline hydrolysis of the intermediate ester. the potent 5-HT1A receptor agonist (1R,2S)-2-(2-hydroxyphenyl)-N,N-dipropylcyclopropylamine 13 was synthesized by this method

1-VINYL-4-METHYL-2,6,7-TRIOXABICYCLOOCTANES: UNSATURATED HOMOENOLATE ANION EQUIVALENTS

The metalation of (E)-1-(2-chlorovinyl)- or (E)-1-(2-bromovinyl)-4-methyl-2,6,7-trioxabicyclooctane with tert-butyllithium produced an unsaturated homoenolate anion equivalent which intercepted alkylhalides, aldehydes, ketones, and lactones to afford β-alkylated or β-acylated orthoesters, which, in turn, furnished β-substituted acrylate esters.
