Allgemeine Beschreibung

Ethyl crotonate on hydroboration yields stereospecifically 2-tritiated 3-hydroxybutyric acid.

Anwendung

Ethyl crotonate was used in chemical-shift imaging during the rapid analysis of multiple samples using multiplex sample NMR. It was used as reagent during the total synthesis of (+/-)-daurichromenic acid.

1. A specimen of stereospecifically 2-tritiated 3-hydroxybutyric acid was prepared by hydroboration of ethyl crotonate. It was assumed that the hydroboration reaction took a syn course and hence that (2R,3S) plus (2S,3R)-3-hydroxy[2 minus 3H1]butyric acid was formed after oxidation and

A modular and concise total synthesis of (+/-)-daurichromenic acid has been accomplished in four steps from ethyl acetoacetate, ethyl crotonate, and trans,trans-farnesal. A series of analogues of this natural product, which has potent anti-HIV activity, were also prepared from ethyl

Developed from crosses between Vitis vinifera and North American Vitis species, interspecific hybrid grape varieties are becoming economically significant in northern areas, where they are now extensively grown for wine production. However, the varietal differences between interspecific hybrids are not
