标 题:Analogs of thromboxane B2 and processes for their synthesis
发明人：KELLY ROBERT C; NELSON NORMAN A
权利人:UPJOHN CO
摘要:The present specification provides novel intermediates and novel processes for the synthesis of various side chain and skeletal analogs of Thromboxane B 2 (11β-homo-11a-oxa-PGF 2 .sub.α). These analogs are particularly and especially useful as reproductive cycle control agents.

摘要:A process for synthesis of a polymeric polyalcohol substantially and preferably built up form polyester units and composed of a monomeric or polymeric initiator molecule to which at least one dentritic branch (dendron) consisting of a number of branching generations is added. The branching generations comprise a polymericor monomeric branching chain extender having three reactive functions of which two are hydroxyl groups. The two hydroxyl groups of the ranching chain extender is acetal protected by reaction between said two hydroxyl groups and an acetal-forming carbonyl compound, preferably an aldehyde. The acetal protected branching chain extender is then employed for addition to the initiator molecule of a first branching generation followed by an optional deprotection of the hydroxyl groups by decomposition of acetals and for addition in repeated steps of further branching generations. Additions of branching generations individually employ an acetal protected branching chain extender synthesized from the same or a different branching chain extender and/or acetal-forming carbonyl compound and addition of a branching generation is optionally followed by addition of a spacing generation.
