Summary:PCT No. PCT/HU86/00068 Sec. 371 Date Aug. 7, 1987 Sec. 102(e) Date Aug. 7, 1987 PCT Filed Dec. 9, 1986 PCT Pub. No. WO87/03595 PCT Pub. Date Jun. 18, 1987.The invention relates to a process for the preparation of compounds of the Formula I (I) (wherein R and R1 stand for an aliphatic acyloxy group comprising 2-5 carbon atoms and optionally substituted by halogen or for an aromatic acyloxy group comprising 7-11 carbon atoms), which comprises reacting a compound of the general Formula II (II) (wherein R2 stands for hydrogen or alkyl comprising 1-4 carbon atoms) with a boron derivative of the Formula III (III) (wherein R3, R4 and R5 stand for an alkyl group comprising 1-4 carbon atoms and optionally substituted by halogen or for an aryl group comprising 6-10 carbon atoms). The new compounds of the general Formula I are useful pharmaceutical intermediates.
