2-(Halomethyl)-4,5-diphenyloxazoles are effective, reactive scaffolds which can be utilized for synthetic elaboration at the 2-position. Through substitution reactions, the chloromethyl analogue is used to prepare a number of 2-alkylamino-, 2-alkylthio-, and 2-alkoxy-(methyl) oxazoles. The 2-bromomethyl analogue offers a more reactive alternative to the chloromethyl compounds and is useful in the C-alkylation of a stabilized (malonate) carbanion as exemplified by a concise synthesis of Oxaprozin.

Oxazole derivatives having Formula I or II are disclosed which are useful as inhibitors of mammalian blood platelet aggregation. STR1 Formula I and Formula XIX compounds are those wherein n is 7-9 and R is hydrogen or lower alkyl. Formula II compounds are those wherein R is hydrogen, lower alkyl or together with CO2 is tetrazol-1-yl; R1 is phenyl or thienyl; X is a divalent connecting group selected from the group consisting of CH2 CH2, CH=CH, and CH2 O; Y is a divalent connecting group attached to the 3 or 4 phenyl position selected from the group consisting of OCH2, CH2 CH2 and CH=CH. Formula XX compounds are those wherein the OCH2 CO2 R moiety is attached to the 3 or 4 phenyl position and R is hydrogen or lower alkyl.
