4-甲氧基-1,3-苯并二氧戊环-5-甲醛 | 4-methoxybenzo[d][1,3]dioxole-5-carbaldehyde | 5779-99-7 | C9H8O4 | 180.16 |
A synthesis of substituted phenylvaleric acids 4 a-e from 1,3-benzdioxolaldehyds 1a -d is described. Treatment with PPA gave benzocycloheptanones 5a-e which gave by reduction and dehydratisation benzocycloheptene 7 a-d. Reactions of benzocycloheptanone 5a and of benzocycloheptenaldehyds 10a-b are reported.
