Abstract
NEW MATERIAL:2-Spiro-1,3-dioxolane compound of formula Ia or formula Ib (X is H, or halogen; Y is halogen, amino, substituted amino, OH, or acyloxy; A is alkylene or alkeynlene which may have heteroatoms of O, N, and S in the chain and may have a substituted group; dotted lines show the presence or the absence of double bond).
EXAMPLE: 4'-Chloromethyl-5-bromo-1-benzenesulfonyl-4, 5, 6, 7-tetrahydroindol-4- spiro-2'-(1, 3)dioxolane of formula IV.
USE: Intermediate for the preparation of aromatic ethers of formula V (vasular dilators, hypotensives, etc.) having a central nervous system stimulating activity.
PROCESS: For example, a cyclohexenone compound of formula IIa or formula IIb is condensed with propanediol of formula III to afford a compound of formula Ia or formula Ib.
