    Ammonia-Promoted Fragmentation of 2-Alkyl- and 2,4-Dialkyl-3-iodo-1- oxocyclohexan-2,4-carbolactones
    摘要:
    2-Alkyl- and 2,4-dialkyl-3-iodo-1-oxocyclohexan-2,4-carbolactones undergo ammonia-promoted fragmentation reactions to provide butenolides, gamma-butyrolactone, and/or, beta,gamma-epoxycyclohexanones. Product distribution is governed by the relative size of the substituents at C-2 and C-4 of the cyclohexanones. Butenolide amide, the major product from the fragmentation, is further converted into their respective piperidinone and pyrrolidine derivatives.

    摘要:
    2-烷基-和2,4-二烷基-3-碘-1-氧代环己基-2,4-碳内酯经历氢氧化锂和烷氧基锂诱导​​的裂解反应,从而提供丁烯内酯,γ-羟基环己烯酮和/或γ-丁内酯。通常,产物分布受两个因素控制:(1)亲核试剂的性质和(2)环己酮在C-2和C-4处取代基的空间体积。氢氧化锂诱导的断裂提供丁烯内酯和γ-羟基环己烯酮。相反,在有限的情况下,锂醇盐促进的断裂会导致主要为5取代的γ-丁内酯以及少量的丁烯内酯。由氢氧化锂诱导的裂解产物在很大程度上受环己酮环的C-2和C-4处取代基的空间体积的影响。

    Fragmentation reactions of keto iodolactones 4 provide access to butenolides 5, 2-alkyl-4-hydroxy-2-cyclohexen-1-ones 6, and butyrolactones 9. Delta(alpha,beta)-Butenolides 5e and 5f were converted to heterocycles 14-16 by way of intramolecular cycloaddition reactions. (C) 1998 Elsevier Science Ltd. All rights reserved.

    Stereoselective dihydroxylation of 2a-2f gives <(cis)under bar>-diols 3a-3f, from which hydroxylactones 5a-5f are obtained by an acid-catalyzed process involving retro aldol-realdolization prior to transesterification. (C) 1998 Elsevier Science Ltd. All rights reserved.
