Zinc chloride catalyzed reactions of chiral piperazine derivatives 4a-d with 1-alkynes and aldehydes give chiral propargylamines in 67-95 % yields with up to 99:1 dr. The chiral propargylamines are converted into chiral allenes by using zinc bromide in sh

The first elimination reactions of silyl enol ethers to lithiated allenes are reported. These reactions allow a direct transformation of readily available silyl enol ethers into functionalized allenes. The action of three to four equivalents of lithium di
