An efficient palladium-catalyzed oxidative nonclassical Heck reaction of arylhydrazines with allylic alcohols via C–N bond cleavage has been successfully developed. This method provides a series of β-arylated carbonyl compounds with broad functional group tolerance under base-free, simple, and mild open air reaction conditions. In the reaction, arylhydrazines with the smaller molecular weight of the

2-propanol-mediated reductive coupling of branched allylic acetates 1a-1o with formaldehyde to form primary homoallylic alcohols 2a-2o with excellent control of regio- and enantioselectivity. These processes, which rely on enantiotopic π-facial discrimination of σ-allyliridium intermediates, represent the first examples of enantioselective formaldehyde C-C coupling beyond aldol addition.
SEGPHOS 修饰的手性铱配合物可催化 2-丙醇介导的支链烯丙乙酸酯 1a-1o 与甲醛的还原偶联,形成高烯丙醇 2a-2o,并具有出色的区域选择性和对映选择性控制。这些过程依赖于 σ-烯丙基铱中间体的对映体 π-面辨别,代表了羟醛加成以外的对映选择性甲醛 CC 偶联的第一个例子。
Structure-activity relationships of cyclic enediynes related to dynemicin A—II. Synthesis and antitumor activity of 9- and 12-substituted enediynes equipped with aryl carbamate moieties
Novel enediyne compounds 4-8, simple analogues of dynemicin A (1) equipped with the phenyl or 4-chlorophenyl carbamatemoiety, were synthesized and evaluated for DNA-cleaving ability, in vitro cytotoxicity, and in vivo antitumor activity. As a result of the SAR study, it was revealed that the size and character of the substituents (R1 and R2) at the C9 position critically influenced both the stability
