    • To test the feasibility of the insertion reaction we selected the more commonly used rhodium(II) acetate as the catalyst. We did not yet try to improve the yield by using other rhodium(II) derivatives or reaction conditions

    • The reduction of the mixture of the two diastereomers of 4c led to only two diastereomers of 10, among four possible. This result is in accordance with the well documented high cis diastereoselectivity of sodium borohydride reduction of β-ketosulfones. Since it was quite unlikely that the success of the chemistry planned to transform 10 into dihydrofuran derivatives, would significantly depend on the cis or trans relationship between the hydroxy-phenylsulfonyl moiety and the phenyl group, at this stage of our work we did not try to assign the stereochemistry of the major and of the minor diastereomer. We further used the former compound obtained in larger amount
