| abstract | NEW MATERIAL:An optically active compound shown by formula I (R 1 is H or readily eliminable protecting group selected from alkenyl, aralkyl, alkyloxymethyl, 1-alkyloxyethyl, hetero atom-containing cyclic alkyl and silyl; X is halogen or R 4 SO 3 ; R 4 is alkyl or aryl; * shows asymmetric carbon atom). n USE: An intermediate for producing prostaglandins by an extremely shorter process than a well-known method. n PREPARATION: A compound shown by formula II (X 1 is halogen; R 3 is readily eliminable protecting group selected from alkyl and aralkyl which may contain halogen-substituted group and two R 3 may be bonded to form cyclic acetal) is made to react with an optically active compound shown by formula III to give a compound shown by formula IV and a protecting group R 1 is introduced to OH thereof to give a compound shown by formula V. Then the acetal part of the compound shown by formula V is hydrolyzed in the presence of a weak Lewis acid to give a compound shown by formula I. n COPYRIGHT: (C)1991,JPO&Japio |
