Stereoselective [8 + 2] Cycloaddition Reaction of Azaheptafulvenes with α-Chloro Aldehydes via N-Heterocyclic Carbene Catalysis
A highly efficient [8 + 2] cycloaddition reaction of azaheptafulvenes with α-chloro aliphatic aldehydes enabled by N-heterocyclic carbene catalysis is presented, delivering cis-cycloheptatriene-fused γ-lactams with good yields, moderate to good diastereoselectivies, and excellent enantioselectivies. This higher order cycloaddition reaction can be readily expanded to the gram scale, and the products

antiproliferative activity on DU‐145 human prostate carcinoma cell line (hit compound potency – 2.9 μM). Medicinal chemistry optimization of two peripheral diversity vectors of the hit molecule, independently, led to SAR generalizations and identification of the ‘best’ moieties. The latter were merged in a single compound that exhibited an over 100‐fold better potency than the hit compound. For the most potent
通过高通量筛选确定了一个新的化学系列,它对 DU-145 人前列腺癌细胞系具有抗增殖活性(命中化合物效力 - 2.9 μM)。对命中分子的两个外围多样性载体的药物化学优化,独立地导致 SAR 概括和“最佳”部分的鉴定。后者合并为单一化合物,其效力比命中化合物高 100 倍以上。对于最有效的化合物,已证实观察到的抗增殖效力与化合物的非特异性细胞毒性无关。
Iridium-Catalyzed 1,3-Hydrogen Shift/Chlorination of Allylic Alcohols
Tandem: Allylic alcohols react with N‐chlorosuccinimide (NCS) in a tandem 1,3‐H shift/CCl bond formation leading to α‐chloroketones and α‐chloroaldehydes. The reactions proceed with complete selectivity to give single constitutional isomers of monochlorinated carbonyl compounds. The utility of the transformation is illustrated by the straightforward synthesis of 4,5‐disubstituted 2‐aminothiazoles
