    • The reaction with aliphatic aldehydes in the present conditions did not afford the expected aldol product; it is known that for those substrates the formation of chlorohydrin may occur (see discussion in Ref. 1)

    • The observed syn stereoselectivity for the reaction in toluene might be explained with the preference for a boat-like transition state instead of a chairlike transition state (see Fig. 1 for a proposed model of stereoselection)
