Synthesis of new cytotoxic aminoanthraquinone derivatives via nucleophilic substitution reactions.
Aminoanthraquinones were successfully synthesized via two reaction steps. 1,4-Dihydroxyanthraquinone (1) was first subjected to methylation, reduction and acylation to give an excellent yield of anthracene-1,4-dione (3), 1,4-dimethoxyanthracene-9,10-dione (5) and 9,10-dioxo-9,10-dihydroanthracene-1,4-diyl diacetate (7). Treatment of 1, 3, 5 and 7 with BuNH2 in the presence of PhI(OAc)2 as catal...
متن کاملElectrophilic Substitution of Aromatic Compounds by Unsaturated Sugar Derivatives
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 Phosphorus Derivatives via Multicomponent Reactions
Stable derivatives of oxaphosphaphenanthrenes were prepared using multicomponent reactions of 3-bromo-2-naphthol, dialkyl acetylenedicarboxylate and trimethyl or triphenyl phosphite under microwave conditions with good yields.
متن کاملSynthesis and Reactions of Triptycenes and Their Derivatives
In order to verify if the triptycyl (the analog of triphenylmethyl in which the three phenyl groups were united to a CH) free radical 1a (Fig. 2.1) should be more instable than the triphenylmethyl radical itself, Bartlett et al. [1] first synthesized triptycene 1 in a low total yield by a multistep route starting from the Diels–Alder addition reaction of anthracene and benzoquinone (Scheme 2.1)...
متن کاملRegioselective Electrophilic Aromatic Substitution Reactions over Reusable Zeolites
Zeolite catalysts can play an important role in the development of greener organic syntheses through their abilities to act as heterogeneous catalysts, support reagents, entrain by-products, avoid aqueous work-ups and enhance product selectivities via shape-selectivity. We have shown that zeolites under modest conditions can have advantages in para-regioselective nitration, alkylation, acylatio...
