希望各位能帮助一下, 感谢!!!
Classify each of the following reactions as stereospecific/stereoselective and/or
regiospecific/regioselective:
我估计(c) diastereospecific (because product has 2 chiral centres) and regiospecific (just guess) ;
(d)regioselective(because LDA can attack either side, but it prefers attacking H on RHS because of steric effect) ;
(e) is enantiospecific (because it has a chiral centre) andregiospecific (just guess),p.s. It is Schmidt Rearrangement reaction.
以下有2题可作参考(答案绝对正确)
