One‐Pot Synthesis of α‐Formyloxy Ketones from Enolizable Ketones
摘要:
One-pot synthesis of alpha-formyloxy tones as well as alpha-acetoxy ketones from enolizable ketones and [hydroxy(tosyloxy)iodo] benzene (HTIB)/polymer supported [hydroxy(tosyloxy)iodo]benzene (PSHTIB) in N,N - dimethylformamide (DMF)/N,N - dimethylacetamide (DMA) in high yields is described.

As a consequence of discrepancies in the literature, further investigations have been made concerning the identities of certain bisalkylthioalkenes and the possible existence of equilibria between the two isomers: R1CH:CH·CH(SR2)2⇌ R1CH(SR2)·CH:CH·SR2(R2= Et or Bun)
A sustainable byproduct catalyzed domino strategy: facile synthesis of α-formyloxy and acetoxy ketones via iodination/nucleophilic substitution/hydrolyzation/oxidation sequences
The sustainable byproduct catalyzed domino strategy has been performed for the facilesynthesis of alpha-formyloxy and acetoxy ketones via iodination/nucleophilic substitution/hydrolyzation/oxidation sequences from simple and readily available aromatic ketones/unsaturated methyl ketones.

and the para-bromo substituted derivatives had the lowest minimum protozoacidal concentrations (8–16 μg/mL). Surprisingly, both enantiomers were found to have high potency suggesting that this compound class could have several modes of action. No correlation was found between the compounds protozoacidal activity and the in vitro epidermal growth factor receptor tyrosine kinase inhibitory potency. This
测试了一系列的6-芳基-吡咯并[2,3- d ]嘧啶-4-胺(43种化合物),其中一些是表皮生长因子酪氨酸激酶抑制剂,使用环境四膜虫菌株作为模型生物对它们的原生动物毒性进行了测试。发现类似物的原酸活性高度依赖于6-芳基环上的4-羟基和4位上的手性1-苯基乙胺取代基。此外,效力受到苯基乙胺的芳族取代模式的影响。 :未取代的,间-氟和对位-溴取代的衍生物的最低原生动物酸浓度最低(8–16μg/ mL)。令人惊讶地,发现两种对映异构体均具有高效力,这表明该化合物类别可具有多种作用方式。化合物的原酸活性与体外表皮生长因子受体酪氨酸激酶抑制能力之间没有相关性。这表明观察到的抗菌作用与其他目标有关。对一组激酶的测试表明了几种替代的作用方式。

Abstract Iridodial is a key intermediate in the biosynthesis of nepetalactone. One of the steps on the pathway prior to the lactonization is a hydride shift from C-1 to C-10. 10-Hydroxycitronellol is a far more efficient precursor than the C-2/C-3 unsaturated analogue.
