diastereoselectivity. The processes are conducted under very simple experimental conditions, only in the presence of K2CO3, in 1,4-dioxane as solvent and undermicrowaveirradiation, and have been applied for the synthesis of a wide structural variety of fused cyclopentanones and cyclohexanones. Moreover, the versatility of this methodology has been demonstrated in the structural modification of androsterone
acids and N-tosylhydrazones from o-(2-oxoalkyl)- and o-(3-oxoalkyl)benzonitriles leads to β,γ-unsaturated indanones and tetralones featuring an α-“all-carbon” quaternary center. The employment of derivatives of α-substituted cyclopentanones and cyclohexanones led to the stereoselective preparation of β,γ-unsaturated tetrahydrocyclopenta[a]inden-8(1H)-ones, hexahydrofluorenones, and hexahydroanthracenones
烯基硼酸与邻-(2-氧代烷基)-和邻-(3-氧代烷基)苄腈的N-甲苯磺酰hydr之间的无过渡金属多米诺反应导致β,γ-不饱和茚满酮和四氢萘酮具有α-“全-碳”四元中心。使用α-取代的环戊酮和环己酮的衍生物导致立体选择性地制备β,γ-不饱和四氢环戊酮[ a ] inden-8(1 H)-ones,六氢芴酮和六氢蒽酮为顺式融合的单一立体异构体。提出了涉及重氮化合物形成/还原性烯基化/ 1,3-硼氢化重排/分子内硼杂氮杂-烯反应的多米诺序列,以证明产物的形成和立体选择性。

stereoselective spirocyclization of the Hajos–Parrish ketone. The common feature of all the new reactions described is the creation of an all‐carbon quaternary center by formation of two Csp3−C bonds on the hydrazonic carbon atom. DFT‐based calculations suggested the occurrence of cascadeprocesses, which involve a diazo compound carboborylation followed by a 1,3‐borotropic rearrangement on an intermediate
通过N-甲苯磺酰hydr和硼酸之间的多米诺环化反应,合成了具有全碳四元桥头中心的多环分子。通过环过环杂环化反应,一般级联反应的变体已被用于制备3-奎宁环酮和相关的生物碱样支架。此外,使用3-氰基丙基和4-氰基丁基硼酸以及α,β-不饱和N-甲苯磺酰基hydr酮通过史无前例的正式[ n +1]环化反应,包括了Hajos-Parrish酮的立体选择性螺环化反应,形成了螺环。所描述的所有新反应的共同特征是通过形成两个Csp 3来创建全碳四元中心-C键合在肼基碳原子上。基于DFT的计算表明发生了级联过程,其中涉及重氮化合物碳羰基化,然后在中间烯丙基硼酸上进行1,3-硼酸重排,并形成新颖的硼氮杂-氮烯环化反应。
