    • 6 at room temperature. The data are given in the experimental. The same sample was heated to 60 °C and the spectrum was recorded. The appearance of the AB system at δ 4.23 revealed the presence of cyclized structure 3e alongside 2e (the ratio of 2e to 3e is 1:1.11). The spectrum was taken again after heating to 100 °C. The ratio of 2e to 3e was 1:1.27. The peak in the spectrum recorded at room temperature corresponding to methoxy group appears as a singlet at δ 3.80. In the spectra recorded after heating a second peak at δ 3.73 was assigned to the methoxy group of 3e.
