The involvement of acidic cellular compartments that function in biosynthetic roles has recently become an important facet in understanding the regulation of glycoconjugate biosynthesis. Treating cells with increasing concentrations of ammonium chloride (1-50 mM) resulted in about a 50% increase in the synthesis and secretion of newly synthesized [3H]glucosamine-labeled and 35SO4-labeled endothelial glycoproteins. In contrast, these increasing concentrations of ammonium chloride resulted in a marked decrease in the synthesis of [3H]glucosamine- and 35SO4-labeled secreted proteoglycans. Thus the apparent neutralization of acidic compartments does not adversely effect glycoprotein biosynthesis.

And how is NH4Cl supposed to be used in any such synthesis of this hypothetical compound

AB - 1,3-Oxazolidines 9 were synthesized by using a solid support. Regioselective ring opening of resin-bound epoxy ether 3 with ammonium chloride followed by nucleophilic substitution with sodium azide gave azido alcohol 7. Reduction of 7 provided 1-amino-2-alkanol 6, which was treated with various aldehydes and acyl chlorides or isocyanates to afford the corresponding 1,3-oxazolidines immobilized on Wang resin. Oxidative cleavage with DDQ from the solid support yielded 1,3-oxazolidines as a mixture of 10 (cis) and 11 (trans). (C) 2000 Elsevier Science Ltd.

A novel multicomponent synthesis of 5-aminooxazole starting from simple and readily available inputs is described. Thus, simply heating a methanol solution of an aldehyde 3, an amine 4, and an α-isocyanoacetamide 5 provided the 5-aminooxazole (1) in good to excellent yield. The reaction of 1 with α,β-unsaturated acyl chloride 13 lead to the formation of pyrrolo[3,4-]pyridin-5-one (2) in a single operation. A triple domino sequence, acylation/IMDA/retro-Michael cycloreversion, is involved in this new scaffold-generating reaction. After the observation that ammonium chloride can significantly accelerate the oxazole formation in toluene, a one-pot four-component synthesis of 2 is developed.
