lates and trapped with a range of electrophiles resulting in either reduction, reduction/aldol, reduction/Claisen condensation or reduction/aldol-Tishchenko products. In addition we demonstrate that 2,2-dichloro-1-arylethen-1-olates undergo counter-ion controlled Darzens condensations, which can be followed by a thermal rearrangement as a route to 1,3-diaryl-3-chloropropane-1,2-diones.
可用RMgX将2,2,2-三氯-1-芳基-乙酮还原为相应的2,2-二氯-1-芳基-1-油酸酯,并用一系列亲电试剂捕集,导致还原,还原/羟醛,还原/ Claisen冷凝或还原/ Aldol-Tishchenko产品。此外,我们证明了2,2-二氯-1-芳基-1-油酸酯会经历抗衡离子控制的Darzens缩合反应,随后可以进行热重排,作为通往1,3-二芳基-3-氯丙烷-1的途径, 2-二酮。
