Permethyl ether 1 from Tolypothrix conglutinata was synthesized following the retrosynthetic analysis of Scheme 1. According to it, we combined aldehyde 3 [prepared from S-glycidol (7); cf. Schemes 2, 3] and lactone 4 (also prepared from S-glycidol (7); cf. the preceding communication[2] and Scheme 4) to the enantiopure and diastereopure trimethoxy lactone 2 (Scheme 5). The CO group of this lactone
