Full textThis work is divided in two main parts which both deal with the use of sulfoxides as chiral auxiliaries in [4+2] heterocycloaddition reactions. The first part is devoted to the synthesis of N-sulfinylimines and their reactivity in normal electron demand heterocycloaddition. One of these compounds, the ethyl (Ss)-(+)-(ptoluenesulfinyl)iminoacetate, proved to be an excellent dienophile towards cyclopentadiene. The cycloaddition occured without a catalyst at room temperature, with a high exo selectivity and a significant facial induction. More over, this reaction led to a nitrogen bicyclic adduct of valuable structure. The work described in the second part has contributed to the development of the synthetic potential of 2-sulfinylmethyloxadienes in organic synthesis, in studying their reactivity as new chiral heterodienes in inverse electron demand [4+2] heterocycloadditions. Indeed, these compounds displayed a good reactivity towards various vinyl ethers and sulfides under Zn12 catalysis, leading to original dihydropyranic adducts in proper yields, with high endo selectivity and satisfactory facial diastereoselectivity. Then, functional modifications of the adducts, via a [2,3]-sigmatropic rearrangement key-step, provided efficient access to diastereopure 2,3-dideoxy-3 -alkyl-glycosides. Furthermore, this methodology was successfully adapted to solid phase conditions by the use of an original supported vinyl ether. Other heterodienes, such as 3,y-ethylenic aketoesters, were also used with good results and, finally, this study clearly showed the posibility to generate structural and functional diversity
