Benzylic-acetoxylation of alkylbenzenes with PhI(OAc)2 in the presence of catalytic amounts of TsNH2 and I2

Treatment of alkylbenzenes with (diacetoxyiodo)benzene in the presence of catalytic amounts of p-toluenesulfonamide or p-nitrobenzenesulfonamide, and molecular iodine in 1,2-dichloroethane at 60 °C gave the corresponding (α-acetoxy)alkylbenzenes in good to moderate yields. The present reaction is a simple method for the introduction of an acetoxy group to the benzylic position of alkylbenzenes.

Copper triflate/t-BuOOAc-catalyzed amidation of allylic and benzylic acetates with sulfonamides

A copper triflate/t-BuOOAc-catalyzed amidation of allylic and benzylic acetates has been developed which is suitable for the coupling of a wide variety of functionalized sulfonamide nucleophiles with acetate electrophiles. The methodology allows for the amidation of benzylic substrates which are not further activated by an additional adjacent alkene or alkyne, enabling simple allylic acetates and primary benzylic acetates to be used as reaction partners.

Optically active aromatic carboxylic acid derivatives and process for producing the same

Disclosed are optically active aromatic carboxylic acid derivatives represented by the formula (I): STR1 (wherein R2 represents an alkoxyalkyl group having 1 to 20 carbon atoms or an alkyl group having 1 to 20 carbon atoms, which alkyl group may be substituted with a halogen atom; represents a number of 1 or 2; m represents a number of 0 or 1; and * indicates asymmetric carbon atom) and a process for producing such derivatives through the following reaction steps: STR2 The optically active aromatic carboxylic acid derivatives represented by the above-described formula (I) are useful as a liquid crystal material and can be also utilized as an intermeidate for the preparation of pharmaceuticals, agricultural chemicals and the like.
