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