With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.2346-26-1,Oxazolidine-2,4-dione,as a common compound, the synthetic route is as follows.
WORKING EXAMPLE 29 In substantially the same manner as in Working Example 11, 3-methoxy-4-[1-(5-methyl-2-phenyl-4-oxazolyl)ethoxy]cinnamaldehyde was condensed with 2,4-oxazolidinedione. The condensate was subjected to catalytic hydrogenation to yield 5-[3-[3-methoxy-4-[1-(5-methyl-2-phenyl-4-oxazolyl)ethoxy]phenyl]propyl]-2,4-oxazolidinedione. NMR(delta ppm in CDCl3): 1.73(3H,d,J=6.5 Hz), 1.7-2.1(4H,m), 2.28(3H,s), 2.59(2H,t,J=7 Hz), 3.85(3H,s), 4.82(1H,dd,J=7&4.5 Hz), 5.32(1H,q,J=6.5 Hz), 6.59(1H,dd,J=8&2 Hz), 6.68(1H,d,J=2 Hz), 6.78(1H,d,J=8 Hz), 7.35-7.5(3H,m), 7.95-8.1(2H,m), 8.66(1H,br s).
2346-26-1, As the paragraph descriping shows that 2346-26-1 is playing an increasingly important role.
