| NEW MATERIAL:The compound of formula I (R is carbon ring or heterocylic group; Z is alkylene, alkenylene, oxyalkylene or aminoalkylene; A is halogen, alkyl, alkenyl, haloalkyl, OH, alkoxy, cyano, amino, etc.; B is O, CO, S, SO or azo; X is halogen; l is 0W5; m is 4W20; α and β are 0W4 and α+β>1; p is 1W2; q is 0W1; when p is 1, then q is 0, and when p is 2, then q is 0W1; etc.). EXAMPLE: 1-Bromo-4-furfuryloxybutane. USE: An intermediate raw material useful to introduce various functional groups into amide compound, amine, OH-substituted compound, etc. PREPARATION: The compound of formula I can be prepared economically in one step by reacting the OH-substituted compound of formula II with the halogen- substituted compound of formula III in an aprotic polar solvent in the presence of a strongly basic substance.

| PURPOSE:To obtain a novel intermediate for a phenyl-substituted prostaglandin E which is useful as a variety of medicines. CONSTITUTION:A compound is represented by formula I[Z<1> is H, a protecting group for OH; X<1> is H, halogen, 1-6C alkoxy, nitro; X<2> is a halogen,-Y<1>h(CR<1> R<2>)mAn(CH2)p, Y<2>q(CR<3>R<4>)rQs (Y<1>, Y<2> are O, S; A is a divalent group; R<1>-R<4> are H, a 1-4C alkyl; Q is H, cyano, OH; h, n, q, s are 0, 1; m, p, r are 0-5]. The compound of formula I is obtained by rearrangement of a furan derivative of formula II in the presence of an acid catalyst, isomerization under acidic or basic conditions and, when needed, protection of the hydroxyl group. A mixture of both antipodes of the compound of formula l is treated with an enzyme to give an optically active compound. | ||||||
