Ring position numbering edit
It says "In an isoxazolidine nitrogen and oxygen occupy positions 1 and 2 in the ring:" but the numbering seems inconsistent with the diagram above where O=1 and N=3. Should it say ""In an isoxazolidine nitrogen and oxygen occupy positions 2 and 1 in the ring (respectively):" - Where is the numbering convention described in WP ? - Rod57 (talk) 12:28, 28 October 2016 (UTC)
Bis-oxazolidines edit
Well I've worked with these compounds for decades. Let us add that the reaction of the amino groups with isocyanates form [[urea)) groups. This goes on in a second as the reactivity between amines and isocyanates is very high. The formation of urethane bonds follows in the next minutes or hours. We should mention that these oxazolidines are "closed by an aldehyde" other than formaldehyde. Usual are isobutyric aldehyde and 2-ethylhexanal. --FK1954 (talk) 13:01, 17 May 2018 (UTC)
