Abstract
NEW MATERIAL:1-Halogeno-2,3,4-trioxybutanes expressed by formula I (R<1>, R<2> and R<3> are protecting groups of hydroxyl; R<2> and R<3> together form acetal; X is halogen; '*' represents optical activity or inactivity). EXAMPLE:(4S,5R)-4-Benzyloxymethyl-5-iodomethyl-2,2-dimethyl-1,3-dioxolan. USE:Useful as a raw material for producing 5,6,7-trioxyheptanoic esters which are useful in synthesis of punaglandin having anticancer action and antiviral action. The 5,6,7-trioxyheptanoic esters are synthesized by adding a compound expressed by formula I to an acrylates. PREPARATION:Diethyl tartrate, whose hydroxy group is protected with acetal, is reduced with lithium aluminum hydride and converted through the compound expressed by formula II and compound expressed by formula III to the aimed compound expressed by formula I.
