C60- and C100-dolichols were synthesized. A -selective Wittig reaction was achieved with high selectivity in a microflow system to realize the scalable supply of the -isoprene unit. An isoprene chain was efficiently elongated by an S2-type coupling between allyl sulfone and allyl chloride using -BuOK. These key reactions enabled the efficient syntheses of dolichols. This study will pave the way for the functional studies of dolichols.
