Eleven optically active 1,2-aminoalcohols 20a–i and 26b–c were prepared from d -phenylglycine via cyclic imines 7b–i (or enamine 7a). The key step of the strategy is the diastereoselective reduction of chiral oxazinones 7a–i.

Various pyrazolo[1,5-a]pyrimidines 1 are prepared by two different ways. Their chemical reduction by sodium borohydride leads generally to 4,5,6,7-tetrahydro compounds 3, while lithium aluminum hydride yields 4,7-dihydro derivatives 2 at room tempera

Formal [3+3] cycloadditions of β-carboxymethylenamino esters with acrolein derivatives give a range of cyclohexa-2,6-dicarboxymethyl-1,3-dienamines that are potential acceptor–donor–acceptor systems.

The reductive amination of appropriate ketopyrrolidines leading to 3,5-dialkylindolizidines usually gives stereoselectively the indolizidine with a cis relative stereochemistry on the piperidine moiety. We report herein unexpected results concerning
