  Benzotriazole- and 1,2,4-Triazole-Stabilized Allylic Anions:  Applications in Syntheses of Functionalized α,β-Unsaturated Ketones, γ-Lactones, γ-Lactams, and β-Substituted Esters

  摘要：

  Deprotonated 1-(benzotriazol-1-yl)-1-ethoxy-2-hexene (7) reacted with alkyl halides, aldehydes, ketones, imines, and alpha-beta-unsaturated esters to give exclusively the alpha-alkylated products 8a-c, 10a,b, 12, 14, 16, and 18a,b, respectively. Without isolation, these products were hydrolyzed under mild conditions to generate the corresponding simple or functionalized alpha,beta-unsaturated ketones 9a-c, 11a,b, 13, 15, 17, and 19a,b. Similar reactions with the phenyl-substituted analog 3-(benzotriazol-1-yl)-3-ethoxy-1-phenyl-1-propene (21) also gave the analogous alpha-products, but they were accompanied by small amount of the gamma-products in most cases. By contrast, deprotonation of the corresponding triazole derivative 29 with butyllithium followed by reactions with alkyl halides, aldehydes, ketones, or imines yielded exclusively gamma-alkylated adducts 32, 34, 36, 38, 40, and 42. Intermediates 32, 34, 36, 38, 40, and 42 were readily converted into beta-substituted esters 33a-c, gamma-lactones 35a,b, 39, 41, and 43, and gamma-lactams 37a-c on hydrolysis.

  trimethylsilyl phosphite (DTMSP) with aldehydes were converted, by treatment with lithium diisopropylamide (LDA) followed by the successive alkylation and alkaline hydrolysis, to carbonyl derivatives involving aldehydes, unsymmetrical ketones, β,γ-unsaturated ketones, and carboxylic acids. β-Substituted carboxylic esters and γ-substituted lactones were prepared by use of the carbonyl addition compounds of DTMSP

  通过用二异丙基氨基锂 (LDA) 处理，然后连续烷基化和碱水解，将二乙基三甲基甲硅烷基亚磷酸酯 (DTMSP) 与醛的羰基加成化合物转化为涉及醛、不对称酮、β,γ-不饱和酮和羧酸的羰基衍生物酸。利用DTMSP的羰基加成化合物与α,β-不饱和醛制备β-取代羧酸酯和γ-取代内酯。
