TRIPHENYLPHOSPHINE CATALYZED AROMATIC ELECTROPHILIC SUBSTITUTION OF 2-HYDROXYACETOPHENONE MEDIATED BY VINYLTRIPHENYLPHOSPHONIUM CATION
Protonation of the highly reactive 1:l intermediate produced in the reaction between triphenylphosphine and dimethyl acetylenedicarboxylate by 2- hydroxyacetophenone leads to vinyltriphenylphosphonium salt, which undergoes aromatic electrophilic substitution reaction with the conjugate base to produce compounds 4,5, and 6 in 1 : 1.2:0.5 ratios

Glycals 1 and 2 react with methoxybenzene in the presence of SnCLj forming ^-substituted C-glycosyl compounds 4 and 5 + 6 respectively. Under similar conditions l -Obenzoylor methyl pent-2-enopyranos-4-uloses (7) and (8) react with electron rich aromatic compounds furnishing either C-glycosyl compounds or C-2 aryl substituted products depending on the nature of the aromatic component as well as...
متن کاملSynthesis of 3-amino-thiochromanes from 4-benzyl 2-thiazolines, via an unprecedented intramolecular electrophilic aromatic substitution.
A one-pot synthesis of various N-substituted 3-amino-thiochromanes from 4-benzyl-2-methyl thiazoline via a thiazolinium salt is described. The obtained 3-amino-thiochromanes are enantiopure, as their precursors derive from chiral 2-aminoalcohols. The reaction involves the formation of a disulfide, which subsequently takes part in an unprecedented intramolecular electrophilic aromatic substitution.
متن کاملElectrophilic Aromatic Substitution of Catechins: Bromination and Benzylation
Relative yields of C-6, C-8. and C-6 and C-8 substituted catechins obtained from the reaction of (+ )-catechin or 3' 4',57-tetra-O-methvl-( + )-catechin with pyridinium hydrobromide-perbromide, bromine. p-hydroxybenzyl al~oh~I, or o-hydroxybenZyI alcohol showed differing selectivities depending upon the electrophile used. Ratios of C-6 to C-8 substituted products were 1 : 1.2 for the reaction o...
