Substituted Tetrahydropyrrolo[2,1-b]oxazol-5(6H)-ones and Tetrahydropyrrolo[2,1-b]thiazol-5(6H)-ones as Hypoglycemic Agents
摘要:
A series of substituted tetrahydropyrrolo[2,1-b]oxazol-5(6H)-one and tetrahydropyrrolo[2,1-b]thiazol-5(6H)-ones was synthesized from amino alcohols or amino thiols and keto acids. A pharmacological model based on the results obtained with these compounds led to the synthesis and evaluation of a series of isoxazoles and other monocyclic compounds. These were evaluated for their ability to enhance glucose utilization in cultured L6 myocytes. The in vivo hypoglycemic efficacy and potency of these compounds were evaluated in a model of type 2 diabetes mellitus (non-insulin-dependent diabetes mellitus), the ob/ob mouse. 25a(2S) (SDZ PGU 693) was selected for further pharmacological studies.

The separation of rac‐o‐chloromandelic acid 1 with enantiopure aryloxypropylamine via diastereomeric salt formation was investigated. (R)‐o‐chloromandelic acid (R)‐1, a key intermediate for the antithrombotic agent clopidogrel, was obtained in 65% yield and 98% ee by Dutch resolution of rac‐1 with (S)‐2‐hydroxyl‐3‐(p‐chlorophenoxy) propylamine (S)‐5 as resolving agent and (S)‐2‐hydroxyl‐3‐(o‐nitrophenoxy)
