摘要

Novel prostaglandin intermediates and process for the production thereof. Compounds, and process for the production thereof, useful in the production of (dl)-[1 alpha -hydroxy-3 beta -(3S-tetrahydropyranyloxy-trans-1-octenyl)-4 alpha -tetrahydropyranyloxy-cyclopent-1 alpha -yl] acetaldehyde hemiacetal and [1 alpha -hydroxy-3 beta -(3S-tetrahydropyranyloxy-trans-1-octenyl)-4 alpha -tetrahydropyranyloxycyclopent-1 alpha -yl] acetaldehyde hemiacetal.
