This paper investigates the thermal degradation of eight linear amines loaded with CO2 and H+. The degradation rate of these amines tends to decrease with chain length. Hexamethylenediamine, the diamine with the longest chain, was found to be the most thermally resistant of the eight amines under CO2 loading. Putrescine was the only amine under acid loading that was not thermally stable, suggesting that the reaction mechanism is initiated by H+. Ethylenediamine, 2-(2-aminoethoxy)ethanamine, hexamethylenediamine, and Diglycolamine reach a thermodynamic equilibrium with their degradation products. Ethylenediamine was also found to be the most corrosive amine tested.

The electrochemical hydroxylation of 1,3-oxazolidin-2-one to 4-hydroxy-1,3-oxazolidin-2-one is reported; a substantial size product is the symmetrical ether derived from the hydroxycompound.An improved synthesis of 3H-1,3-oxazol-2-one has been developed; nothing more is involved than boiling the readily available 4-methoxy-1,3-oxazolidin-2-one with an excess of acetic acid and one equivalent of acetic anhydride, evaporation of the solvents and recrystallization of the residue.The mechanism of the reaction is discussed.In a reinvestigation of the known conversion, by acetic anhydride, of 4-methoxy-1,3-oxazolidin-2-one to N-acetyl-1,3-oxazol-2-one, we have uncovered the formation of two 3,4′-bioxazole side products <3-(2-oxo-1,3-oxazolidin-4-yl) 1,3-oxazol-2-one and its N-acetyl derivative>, especially in the presence of added acids.We have found that N-formyl-1,3-oxazol-2-one can be made in good yield by treatment of 3H-1,3-oxazol-2-one with a mixture of formic acid and acetic anhydride (“acetic formic anhydride”) in the presence of 4-(N,N-dimethylamino)pyridine; the formation of an intermediate phosphonate derived from 3H-1,3-oxazol-2-one, as described in the literature synthesis of N-formyl-1,3-oxazolone, is superfluous.

Compounds 6a-c, characterized by the presence of an ethereal group at C-3, show HIV reverse transcriptase (RT) inhibitor activity in the nanomolar range as well as HIV-infection inhibitor activity in the low micromolar with no toxicity. In the same context, compound 7b shows only a negligible inhibition of RT HIV.

Previous structure-activity relationship studies involving a series of lactone-based muscarinic ligands identified a lead compound containing a diphenylmethylpiperazine moiety (4; IC50 = 340 nM). The purpose of the present work is to investigate 1,3-benzodioxoles, 4,4-diethyl substituted tetrahydrofurans, 5-substituted oxazolidinones and chromones as bioisosteric replacements for the lactone ring in a novel series of muscarinic ligands. The approach provided compounds with improved % inhibition values and identified a non-selective muscarinic ligand with an IC50 value of 280 nM. The structure-activity relationship for this new series will be discussed. Selected compounds were evaluated in preliminary assays for subtype selectivity and were found to be non-selective.

A novel method for metal-free oxothiolation of ynamides to construct oxazolidine-2,4-diones bearing sulfur-substituted quaternary carbon atoms has been developed. It represents a rare C-O bond cleavage of ynamides, as well as a facile and tandem approach for the formation of C-O, C-S, and C-Cl bonds. This redox-neutral protocol can be applied to the synthesis of multisubstituted oxazolidine-2,4-diones with good chemoselectivity and good yields of isolated products under mild conditions.

The synthesis and structure-activity relationship analysis of a novel class of amide-based biaryl NR2B-selective NMDA receptor antagonists are presented. Some of the studied compounds are potent, selective, non-competitive, and voltage-independent antagonists of NR2B-containing NMDA receptors. Like the founding member of this class of antagonists (ifenprodil), several interesting compounds of the series bind to the amino terminal domain of the NR2B subunit to inhibit function. Analogue potency is modulated by linker length, flexibility, and hydrogen bonding opportunities. However, unlike previously described classes of NR2B-selective NMDA antagonists that exhibit off-target activity at a variety of monoamine receptors, the compounds described herein show much diminished effects against the hERG channel and alpha1-adrenergic receptors. Selections of the compounds discussed have acceptable half-lives in vivo and are predicted to permeate the blood-brain barrier. These data together suggest that masking charged atoms on the linker region of NR2B-selective antagonists can decrease undesirable side effects while still maintaining on-target potency.

Practical syntheses of a series of novel ynamides and allenamides are described here. While a base-induced isomerization protocol of propargyl amides leads to an array of chiral and achiral allenamides, ynamides are prepared from enamides via bromination followed by base-induced elimination of the Z-bromoenamides. These ynamides and allenamides possess improved thermal stability compared to ynamines and allenamines. They can be isolated, purified, and handled with ease, and thus, should be synthetically more useful than traditional ynamines and allenamines.
