Abstract
Methyl cinnamate ‐3‐^14^C is reduced smoothly in excellent yield to cinnamyl alcohol ‐3‐^14^C by aluminum hydride. without attack of the double bond. After purification by column chromatography cinnamyl alcohol ‐3‐^14^C is obtained with a radioactive overall yield of 65% based on cinnamic acid ‐3‐^14^C, specific activity = 9 mCi/mM.
