Studies on a urea-directed Stork-Crabtree hydrogenation. Synthesis of the C1-C9 subunit of (+)-zincophorin

(Chemical Equation Presented) A detailed account on the stereoselective synthesis of the C1-C9 subunit of (+)-zincophorin is described here. This approach features the first application of a stereoselective inverse electron demand hetero-[4 + 2] cycloaddi

Efficient preparations of novel ynamides and allenamides

Practical syntheses of a series of novel ynamides and allenamides are described here. While a base-induced isomerization protocol of propargyl amides leads to an array of chiral and achiral allenamides, ynamides are prepared from enamides via bromination followed by base-induced elimination of the Z-bromoenamides. These ynamides and allenamides possess improved thermal stability compared to ynamines and allenamines. They can be isolated, purified, and handled with ease, and thus, should be synthetically more useful than traditional ynamines and allenamines.

First stereoselective inverse demand [4 + 2] cycloaddition reactions of novel chiral allenamides with heterodienes. Preparation of highly functionalized 2-arylpyranyl heterocycles

matrix presented The first stereoselective inverse demand [4 + 2] cycloaddition reactions of chiral allenamides with heterodienes are described here. These reactions lead to stereoselective synthesis of highly functionalized pyranyl heterocycles. A mechan
