37830-90-3, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,37830-90-3 ,4,5-Dimethyl-1,3-dioxol-2-one, other downstream synthetic routes, hurry up and to see

Name is 4,5-Dimethyl-1,3-dioxol-2-one, as a common heterocyclic compound, it belongs to Dioxole compound, and cas is 37830-90-3, its synthesis route is as follows.

EXAMPLE 1 Preparation of 4-chloro-4-methyl-5-methylene-1,3-dioxolane-2-one (III) To a solution of 50 g of 4,5-dimethyl-1,3-dioxolene-2-one (IV)(Synthesised by the method described in Tetrahedron Letters, 1701-1704 (1972)) in 350 ml of methylene chloride was added 65 g of sulfuryl chloride dropwise over 1 hour at 40¡ã-42¡ã C. The mixture was stirred for one hour at the same temperature and then evaporated in vacuo to remove the solvent. The resulting residue was distilled in vacuo to obtain 42.1 g (65percent of theory) of 4-chloro-4-methyl-5-methylene-1,3-dioxolane-2-one (III) as a colorless oil. B.p. 45¡ã-48¡ã C./2 mmHg. IR(CHCl3)nu(cm-1): 1820, near 1695 etc. NMR(CDCl3, delta(ppm)): 2.19(3H, s, CH3), STR5
