✦ Synopsis

According to the procedure described in the previous communication' S-substituted propenal derivatives are readily available from 1-bromo-2-ethoxycyclopropyllithium (I) and electrophiles .

Starting with aldehyde II we can easily obtain the product of type III which is now disclosed to be a particularly useful common intermediate for the synthesis of o, p-unsaturated aldehyde moiety of homoterpenoid (IV) and terpenoid (VI) structure.
