| titleOfInvention | Novel isoindoline derivative and production thereof |
| abstract | NEW MATERIAL:The compound of formula I (R is H, lower alkyl, alkanoyl, aralkyl, alkylsulfonyl or arylsulfonyl; R 1 is H or OH-protecting group) or its salt. n EXAMPLE: 5,6-Dihydroxyisoindoline. n USE: Useful as an intermediate raw material for a cephalosporin derivative (an antibacterial agent) having 5,6-dialkanoyl-2-methylisoindoliniomethyl group. n PREPARATION: The compound of formula I can be produced by reacting the compound of formula II (R 2 is OH-protecting group; R 3 is lower alkyl, aralkyl or alkyl- or arylsulfonyl) with formaldehyde and hydrogen halide, dehydrohalogenating the obtained compound of formula III (X is halogen; n is 0 or 1) to the compound of formula IV, removing the protecting group, if necessary, and subjecting the product successively to acylation, N-alkylation and N-aralkylation reactions. n COPYRIGHT: (C)1987,JPO&Japio |
