Participants

Reaction Steps

21.5 g (0.25 mol) of cyclobutane-cis-1,2-diol, 47.8 g (0.26 mol) of orthobenzoic acid trimethyl ester and 0.5 g of benzoic acid are heated to 100° to 150° C. in the course of 3 hours. The methanol which forms is distilled off continuously. The residue is subjected to fractional distillation and gives 40.0 g (78%) of 3-methoxy-3-phenyl-2,4-dioxa-bicyclo[3,2,0]heptane (stereoisomer mixture) of boiling point0.7 92°.
