Copper?? No!! Organocatalysis: For the first time, organocatalytic addition of masked alkyl chains to α,β‐unsaturated aldehydes is reported (see scheme). The addition of bisphenylsulfonylmethane takes place in high yields and with excellent enantioselectivities. Furthermore, this methodology allows the synthesis of isotope‐enantiomers.
铜??不!!有机催化:对于第一次,有机催化加成掩蔽烷基链α,β不饱和醛的报道(参见方案)。双苯基磺酰基甲烷的添加以高收率和优异的对映选择性进行。此外,这种方法可以合成同位素对映体。
