Turning the diols: Enantiomerically pure bifunctional reagents I and ent‐I undergo asymmetric aldehyde allylation followed by IrI‐catalyzed enantioselective decarboxylative allylic etherification to give differentiated syn‐ and anti‐1,3‐diols with complete control of the absolute and relative stereochemistry (see scheme; PMP=para‐methoxyphenyl, dbcot=dibenzo[a,e]cyclooctatetraene, DBU=1,8‐diazabicyclo[5
转变二醇:对映体纯的双官能试剂I和ent - I进行不对称醛烯丙基化,然后用Ir I催化的对映选择性脱羧烯丙基醚化反应,从而生成完全控制绝对和相对立体化学的合成的顺式和反式1,3-二醇(参见方案; PMP =对-甲氧基苯基,dbcot =二苯并[ a,e ]环辛酸酯,DBU = 1,8-二氮杂双环[5.4.0] undec-7-ene)。
