Synthesis and absolute configuration of (-)-normalindine

The first chiral synthesis of the Strychnos and Ophiorrhiza alkaloid (-)-normalindine has been accomplished through a route starting from L-alanine methyl ester and exploiting intramolecular oxazole-olefin Diels-Alder reaction. As a result, the absolute stereochemistry of normalindine has been defined as represented by formula (-)-1.

A straightforward preparation of chiral 5-(aminomethyl)oxazole derivatives from α-amino esters and α-lithiated isocyanides

An efficient and general preparation of several chiral N-protected 5- (aminomethyl)oxazoles has been accomplished by treatment of N-protected α- amino esters with α-lithiated isocyanides, obtained by metalation of methyl and benzyl isocyanides with BuLi or of ethyl isocyanide with lithium diisopropylamide.
