(E)-1-Benzotriazolyl-3-(phenylsulphonyl)-1-propene (6) has been synthesized and its alkylation was studied. The results showed that the phenylsulphonyl group is a more powerful α-directing group than the benzotriazolyl group in the corresponding 1,3-dihetero-stabilized allyl anion.
合成了(E)-1-苯并三唑基-3-(苯基磺酰基)-1-丙烯(6),并对其烷基化进行了研究。结果表明,在相应的1,3-二杂稳定的烯丙基阴离子中,苯磺酰基比苯并三唑基是更有效的α-导向基团。
