Abstract
Acetylenic 2-oxazolidinones. Title cpds. of formula (I) may be prepd. by the reaction of phosgene with a cpd. of formula (II) in presence of base : (where R represents a 1-6C aliphatic gp., a gp. -(CH2)n-NR1R2 (where n is 1-4 and R1 and R2 are aliphatic gps. or together with the N form morpholine, piperidine or pyrrolidine), an araliphatic gp., an alpha- or beta-naphthyl gp. or a benzene ring which may be substd.). In an example, 48 g. (II) R = 4-Cl phenyl in toluene with K2COo was treated with 200 ml. 20% phosgene in toluene to give (I) m.pt. 96 degrees C.
