A flexible variant of the Pictet-Spengler reaction employing oxazinanes as
synthetic equivalents of several carbonyl compounds has been developed. Usi
ng acid catalyzed one pot condensation of perhydro-1,3-heterocycles various
1,3-disubstituted and 1,2,3-trisubstituted-1,2,3,4-tetrahydro-beta -carbol
ines (THBCs) have been synthesized diastereoselectively. (C) 2001 Elsevier
