Birkinshaw, Timothy N. published the artcileSpectrometric and chemical studies of 5-acyl- and 5-nitroso-2-(N,N-disubstituted amino)thiazoles, Formula: C3H8N2S, the publication is Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) (1988), 2209-12, database is CAplus.
The conformational preferences of title compounds I [e.g., R = NMePh, R1 = Me, R2 = Ph, (II); R = NMePh, R1 = Ph, R2 = Me] were established by IR spectrometry and a crystallog. examination of II. In solution, I (R1 = Me, aryl; R2 = aryl) exist predominantly or entirely in the carbonyl O,S-anti form; the syn rotamer is the main form of I (R1 = aryl, R2 = Me), but ?15% of the anti rotamer is present. Nitrosation of 4-aryl-2-(dimethylamino)thiazoles to the 5-nitroso derivatives is discussed, and evidence for nitroso-oximino isomerization in a similar reaction is given. The rotational barrier of the dimethylamino group is unexpectedly high (¦¤G298? = 69 kJ mol-1), exceeding even that of the 5-(trifluoroacetyl) analogs.
