Reaction Steps

Example 8 was repeated except for using 20.9 g (137 mmoles) of 3-methyl-5-chloro-1,4-pentanediol and 4.94 g (28.6 mmoles) of 4-chloro-o-xylylene glycol, instead of 19.0 g (137 mmoles) of 5-chloro-1,4-pentanediol and 3.95 g (28.6 mmoles) of o-xylylene glycol, respectively, to obtain spiro[7-chloro-1,5-dihydro-2,4-benzodioxepin-4'-methylene-5'-methyl-3,2'-[1,3]dioxepane].
