The alkylation of heterocyclic compounds is important for the synthesis of various biologically active compounds. In this paper, we present the development of a Pd/C-catalyzedalkylation of heterocyclic compounds using alcohols as the alkylating agents. This method gives the corresponding alkylated heterocyclic compounds in high yields (up to 99 %). The commercially available catalyst can be recovered

An environmentally benign alkylation of barbituric acids via “borrowing hydrogen” process with ruthenium catalysis has been established. The corresponding 5-(alkyl)barubituric acids were obtained in good to excellent yields with low catalyst loading. Various substrates including aliphatic alcohols were tolerated in the present catalytic system. A novel method for construction of barbituric acid-fused

Aspects of the present disclosure include methods of reducing the deleterious impact of a target gene in a cell, such as the deleterious activity of a mutant extended nucleotide repeat (NR) containing target gene in a cell by contacting the cell with an effective amount of a tetrahydrocarbazole compound. The deleterious activity (e.g., toxicity and/or dis-functionality of products encoded thereby) of a mutant extended NR containing target gene may be reduced, e.g., by reducing (and in some instances differentially, including selectively, reducing) the production or activity of toxic expression products (e.g., RNA or protein) encoded by the target gene. Kits and compositions for practicing the subject methods are also provided.

Through systematic exploration of reaction conditions, very efficient preparative procedures for obtaining large quantities of substituted 5-alkyl and 5-benzylbarbituric acids were developed. The procedure involves a two step preparation in which the second step is zinc dust/acid reduction. For preparation of 5-alkylbarbiturates, the first step is the preparation of either 5-acyl or 5-alkylidenebarbiturate
