Concomitant ultrasonic irradiation during the Simmons‐Smith reaction facilitated the cyclopropanation of ethylenic fatty esters and triglycerides. Methyl ricinoleate furnished predominantly the corresponding hydroxy cyclopropanoid ester when the reaction was carried out at 85–95 C under ultrasound in the presence of zinc, while a C 18 furanoid fatty ester gave a novel tricyclo derivative (methyl 9,12‐epoxy‐9,10;11,12‐dimethanooctadecanoate).
