New compounds useful as intermediates for biologically-active compounds have the formula I
wherein Y is a group having the formula -CH2X in which X is F, Cl, or Br, or Y is a group having the formula
in which R2 is F, Cl or Br and R3 is H. F, Cl, Br or a group having the formula -CR4R5R6, in which R4, R5 and R6, independently, are F, Cl or Br;
A is H, OH, SH, F, Cl, Br or a group -OR7 or -SR7 in which R7 is C1-C4 straight- or branched chain alkyl, C2-4 straight- or branched chain alkyl substituted with 1 to 3 F, Cl or Br atoms, or A is a group -NR8R9 in which R8 and R9, independently, are H, C1-C4 straight- or branched chain alkyl or C3-C4 alkenyl, or R8 and R9 together may form a C3-C7 polymethylene chain, which is optionally interrupted by an oxygen atom; as well as salts of compounds of formula I with acids; provided that:
when Y is CH2F, then A is as hereinbefore defined other than OH, Cl or OCH3.
