A curious and noticeable structural feature in Schiff bases from 2-aminoaldoses is the fact that imino tautomers arranged equatorially in the most stable ring conformation exhibit a counterintuitive reverse anomeric effect (RAE) in the mutarotational

This paper describes the synthesis and structural elucidation of 1,3-oxazolidines derived from tris(hydroxymethyl)aminomethane (TRIS) and pyridine-based aldehydes. Divergent results were obtained with other formylpyridines, such aspyridoxal, in which

Despite the comprehensive literature and enormous versatility of chiral imines derived from aminosugars and aldehydes, the corresponding counterparts generated from ketones remain an underestimated research subject. Filling in the gap, this manuscrip

A series of chiral imines derived from 1-amino-1-deoxyalditols such as d-glucamine, a rather unexplored raw material from the chiral pool, have been serendipitiously transformed into a novel family of N-acetyl-1,3-oxazolidines by means of an unexpect

The conformational population of Z and E isomers of the amide bond in N-acetyl oxazolidines is dictated by the electronic nature of the vicinal aryl ring. Experimental and theoretical data support a rationale based on a strong and stereodirecting cha
