    Stereoselective synthesis of piperidinone and quinolinone systems via ring opening reactions using TiCl4/silyl reagents
    摘要:
    Titanium(IV) chloride and silyl reagents mediated regio- and chemoselective ring opening reactions of oxa-bridged piperidinone ring systems were demonstrated. This methodology interestingly undergoes the stereoselective ring opening at the C-O bond of oxa-bridged piperidinone ring systems. Study of TiCl4 with hydride or non-hydride silyl reagents furnished the product with selectivity. This protocol is highly valuable to synthesize a range of stereoselective piperidinones, quinolinones ring systems. (C) 2011 Elsevier Ltd. All rights reserved.

    铑类胡萝卜素与羰基化合物的串联环化-环加成行为:新型环氧桥联四氢吡喃酮骨架结构的立体选择性研究。
    摘要:
    本文介绍了在羰基化合物存在下,由α-重氮酮产生的羰基串联反应的研究和立体选择性研究。铑类胡萝卜素的分子内环化反应生成了瞬态的五元或六元环羰基内酯偶极子,该偶极子与各种双极性亲子化合物(例如芳香族醛15,α,β-不饱和醛18/24,α)有效地进行了1,3-偶极环加成反应。 ,β-不饱和酮27/28/31和二烯酮34。瞬态羰基酰化物与各种芳族醛进行环加成反应,以非对映选择性的方式提供了多种环氧桥联的四氢吡喃酮环系统。羰基化物与α的环加成,β-不饱和醛18/24或二烯酮34以化学选择性的方式提供了C = O加成产物,尽管在上述双亲性化合物中存在C = C键。备选地,用α,β-不饱和酮27/28对羰基酰基进行的环加成提供了C = O和C = C的环加成产物。羰基化合物与羰基化合物的环加成反应收率很高,并且被发现具有很高的区域选择性和立体选择性。进行了单晶X射线分析,以明确确定新型环氧桥联的四氢吡喃酮环系统35a

    Tandem cyclization–cycloaddition reactions of α-diazo ketones with macrocyclic olefins in the presence of rhodium(II) acetate catalyst led to the oxanorbornane fused macrocyclic di- or tetralactone ring systems in moderate yield. This forms the first example of 1,3-dipolar cycloaddition reactions with a macrocyclic olefin as a dipolarophile, affording a variety of new oxanorbornane fused macrocycles

Intermolecular 1,3-dipolar cycloaddition reactions of five-membered-ring cyclic carbonyl ylides with indole and substituted indoles afforded hexahydro-2H-carbazol-2-ones in a regioselective manner. Similarly, reactions of cyclic carbonyl ylides were carried
