A modified Mannich reaction has been developed for the synthesis of Mannich bases and benzoxazines via the oxidative hydroxylation of arylboronic acids and subsequent coupling with paraformaldehyde and amines in one pot. This modified Mannich reaction is easily carried out to afford the target products in good to excellent yields and tolerates a variety of functional groups.

A Cu(II)-catalyzed ortho-selective functionalization of free phenols with trifluoroborates to afford Csp2-Csp3 coupling products under mild conditions has been developed. A variety of functional groups on the phenol and the potassium aminomethyltrifluoroborate substrates were found compatible, furnishing the corresponding products in moderate to excellent yields. A single-electron transfer radical coupling mechanism involving a six-membered transition state is proposed to rationalize the high levels of ortho-selectivity in the reaction. This protocol provides straightforward access to ortho-aminomethyl-substituted phenols, unnatural amino acids and other bioactive small molecules.

Regioselectivity in Mannich reaction of 4-, 3-, and 2-substituted phenols with typical heterocyclic amines are investigated under reaction conditions developed by us. Phenol and 4-alkyl, and 4-chlorophenols in the title reaction predominantly gave the corresponding 2-(aminomethyl)phenols, while 4-methoxyphenol afforded, in addition to the mono(aminomethyl)phenols, a considerable amount of the bis adducts. Peculiarly enough, 3-methylphenol with amines afforded 3-methyl-4-(aminomethyl)phenols whereas 2-methylphenol produced 2-methyl-6-(aminomethyl)phenols.

Electronic perturbation of quinone methides (QM) greatly influences their stability and in turn alters the kinetics and product profile of QM reaction with deoxynucleosides. Consistent with the electron-deficient nature of this reactive intermediate, electron-donating substituents are stabilizing and electron-withdrawing substituents are destabilizing. For example, a dC N3-QM adduct is made stable over the course of observation (7 days) by the presence of an electron-withdrawing ester group that inhibits QM regeneration. Conversely, a related adduct with an electron-donating methyl group is very labile and regenerates its QM with a half-life of approximately 5 h. The generality of these effects is demonstrated with a series of alternative quinone methide precursors (QMP) containing a variety of substituents attached at different positions with respect to the exocyclic methylene. The rates of nucleophilic addition to substituted QMs measured by laser flash photolysis similarly span 5 orders of magnitude with electron-rich species reacting most slowly and electron-deficient species reacting most quickly. The reversibility of QM reaction can now be predictably adjusted for any desired application.

Synthesis of phenols and naphthol with n-morpholinomethyl pendants and their dimethylgallium complexes: Crystal structure of dimethylgallium-[4-nitro-2-(n-morpholinomethyl)-1-phenoxide]

The one-pot Mannich reaction was used to synthesize 2-(n-morpholinomethyl)-1-phenol (1a), 4-methyl-2-(n-morpholinomethyl)-1-phenol (1b), 4-chloro-2-(n-morpholinomethyl)-1-phenol (1c), 4-nitro-2-(n-morpholinomethyl)-1-phenol (1d), and 1-(n-morpholinomethyl)-naphthol (1e). The dimethylgallium complexes of these compounds have been prepared, and compound 2d has been determined by X-ray crystallography. The complex 2d crystallized with one unit having two identical molecules which have intermolecular contacts between the two phenyls caused by face to face π-π stacking. The Ga-O bond distances are noticeably shorter than in the other dimethylgallium phenoxides reported.
