## Abstract The treatment of the α‐oxoketene dithioacetal sugar derivatives 2 and 7 with concentrated hydrochloric acid in THF leads to the open‐chain uloses 3 and 8. The reaction mechanism can be rationalized as a retro‐aldol reaction. This rationalization was supported by reacting 2 and 7 with DC

Since the C 15 b-end-group aldehyde 10 ((b-ionylidene)acetaldehyde), an excellent intermediate in the syntheses of retinoids, can be synthesized in many ways from b-ionone, and since the corresponding acyclic C 15 y-end-group aldehyde 5 can easily be synthesized from citral (1) (Scheme 3), we applie
