Efficient synthesis of 4-substituted-ortho-phthalaldehyde analogues: toward the emergence of new building blocks
Beilstein J. Org. Chem. 2019, 15, 721–726, doi:10.3762/bjoc.15.67
- – National Council for Scientific Research – B. P. 11- 8281, Riad El Solh 1107, 2260 Beirut, Lebanon 10.3762/bjoc.15.67 Abstract 4-Methoxy-ortho-phthalaldehyde and 4-hydroxy-ortho-phthalaldehyde are potentially useful molecules for fluorimetric analysis of a variety of amines and for the elaboration of
- complex molecular architectures. Nevertheless, literature generally describes their synthesis in very low yield (below 5%), mainly due to the inefficiency of the last oxidation step. In this paper, we report a reliable synthesis of 4-substituted-ortho-phthalaldehyde analogues in 51% overall yield owing to
- ; hydroxy group protection; 4-hydroxy-ortho-phthalaldehyde; ortho-phthalaldehyde; oxidation; Introduction Benzene-1,2-dicarboxaldehyde, also called ortho-phthalaldehyde (OPA) was employed in different domains such as in analytical and organic chemistry. In fact, it is one of the most commonly used
Nucleophilic fluoroalkylation/cyclization route to fluorinated phthalides
Beilstein J. Org. Chem. 2018, 14, 182–186, doi:10.3762/bjoc.14.12
- and hexafluoroacetone to give 3-(trifluoromethyl)phthalide derivatives [11]. In 2006, Pedrosa et al. reported the nucleophilic trifluoromethylation of protected ortho-phthalaldehyde, followed by deprotection and oxidation to afford 3-(trifluoromethyl)phthalide [12]. Pohmakotr et al. demonstrated the
- asymmetric synthesis of 3-(trifluoromethyl)phthalide (1a) using a chiral auxiliary was published to date. In 2006, Pedrosa and co-workers discribed the diastereoselective nucleophilic trifluoromethylation of aldehyde 5, which was prepared by condensation of ortho-phthalaldehyde with (−)-8-benzylaminomenthol
