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