The rearrangement of allylic sulphinates to sulphones is facilitated by palladium catalysis, treatment of the chiral trans-and cis-allyl sulphinates (S)-(–)-(1a)-(1c), and -(1e), and(S)-(–)-(1b)and -(1d)with a catalytic amount of the palladium catalysts (3)and(5)providing the corresponding chiral allyl sulphones,(S)-(+)-and(R)-(–)-(2a–c), respectively, in good yields; exceptionally the palladium catalysis
烯丙基sulphinates的至砜重排是通过钯催化,治疗促进了手性反式-和顺式-烯丙基sulphinates(小号) - ( - ) - (1A) - (1C),和- (1E)和(小号) -(-)-(1b)和-(1d),催化量的钯催化剂(3)和(5)提供相应的手性烯丙基砜,(S)-(+)-和(R)-(- )-(2a – c),分别以高产;(S的重排的钯催化。)-(–)-(1f)产生了(S)-(+)-(2c)。
