The 3-C(3)strategy involves (i) Pd(0)/SnX2 (X = Cl, Br) mediated generation of allyltin(IV) from allyl bromide in anhydrous DCM, (ii) formation of homoallyloxytin(IV) intermediate I from allyltin(IV) and an aldehyde, and (iii) coupling of I with an aldehyde, an aryl epoxide or an arene as the third partner to afford tetrahydropyrans, benzyl tetrahydropyrans or 4,4-diaryl-but-1-enes, respectively.
