✦ Synopsis

Abstract

The stereo‐ and regiochemical course in the [2+4]cycloaddition of the chiral alkylidene malonic ester 1 to selected derivatives of (2__E__, 4__E__)‐4‐methyl‐2, 4‐hexadien‐l‐ol (2) and (2__E__, 4__E__)‐4‐methyl‐2, 4‐hexadien‐l‐al (12) has been investigated. The results are discussed on the basis of semiquantitative PMO theory.
