Abstract

Dihydroquinoline cpds. of the formula (I) are new. R is cyclopropyl, -CH2CR5R6R7 or phenyl opt. mono- or di-substd. by halogen; R5, R6 and R7 are H or halogen; R1 and R2 are halogen, 2-6C aliphatic acyloxy opt. substd. by halogen, or 7-11C aromatic acyloxy; R3 is Cl or F; R4 is H or F. Pref. (I) are prepd. by reacting a cpd. of the formula (II) with HBF4, or BX3 or an ether complex of BX3 (X is F, Cl or Br) or a cpd. of the formula B(OCOR9)3 where R9 is 1-5C alkyl opt. halo substd. or 6-10C aryl. R8 is H or 1-4C alkyl. Reaction may be effected in water (for HBF4) or an organic solvent (for the other reagents).
