Yield: 56% ， 42%

Reaction Conditions:

Stage #1:methanol;benzyl allyl ether with oxygen;ozone at -78;
Stage #2: with semicarbazide hydrochloride at -50 - 20; for 24 h;

Steps:

Ozonation of Allyl Aryl Ethers Ia and Ib
General procedure: (2) An ozone-oxygen mixture was bubbled through a solution of 10.00 mmol of ethers Ia or Ib in50 mL of MeOH at -78°C until blue color appeared.The reaction mixture was purged with argon, 3.88 g(35.00 mmol) of NH2C(O)NHNH2 HCl. HCl was added at -50°C. The mixture was stirred at ambient temperature for 24 h. The reaction mixture was evaporated, the residue was dissolved in 100 mL of CHCl3, washed with 2 (to pH ≈ 7), and dried with Na2SO4. After evaporation, ether I produced 1.86 g of a mixture of compounds II and IV in 40 : 60 ratio(according to GLC and NMR), column chromatography (Si2, PE, PE : MTBE = 5 : 1, 4 : 1) afforded0.74 g (42%) of ester IIa and 1.09 g (56%) of acetal IV.After evaporation, ether Ib produced 1.64 g of a mixture of compounds IIb and IVb in 25 : 75 ratio (according to GLC and NMR data), column chromatography (Si2, PE, PE : MTBE = 5 : 1, 4 : 1) gave 0.40 g (24%)of ester IIb and 1.15 g (63%) of acetal IVb.
