The present invention concerns compounds of formula (I) a stereochemically isomeric form thereof, an N-oxide form thereof or a pharma-ceutically acceptable acid addition salt thereof, wherein —a1═a2—a3═a4— is a bivalent radical wherein one or two of a1 to a4 are nitrogen and the remaining a1 to a4 are —CH═; —Z1—Z2— is a bivalent radical; —A— is a bivalent radical of formula —N(R6)—Alk2— or a 5, 6 or 7-membered saturated heterocycle containing one or two nitrogen atoms; R1, R2 and R3 are each independently selected from hydrogen, C1-6alkyl, hydroxy, halo and the like; Alk1 and Alk2 are optionally substituted C1-6alkanediyl; R5 is a radical of formula (d-1), (d-2), (d-3), (d-4), (d-5) wherein n is 1 or 2; p1 is 0, and p2 is 1 or 2; or p1 is 1 or 2, and p2 is 0; X is oxygen, sulfur or ═NR9; Y2 is oxygen or sulfur; R7 is hydrogen, C1-6alkyl, C3-6cycloalkyl, phenyl or phenylmethyl; R8 is C1-6alkyl, C3-6cycloalkyl phenyl or phenylmethyl; R9 is cyano, C1-6alkyl, C3-6cyclo-alkyl, C1-6alkyloxycarbonyl or aminocarbonyl; R10 is hydrogen or C1-6alkyl; and Q is a bivalent radical. Processes for preparing said products, formulations comprising said products and their use as a medicine are disclosed, in particular for treating conditions which are related to disturbed fundic accomodation.

A variety of 3-substituted-2,3-dihydro-1,4-dioxino-pyridines (3) have been synthesized from the readily available 2-chloro-3-oxiranyl-methoxypyridine (1).Treatment of this epoxide by various nucleophile reagents provided alcohols (2a-i) which, by displacement of the chlorine, gave the desired products (3a-i) in satisfactory yields.
