Traus-cinnamaldehyde

Fo understand the NMR spectrum of traus-cinnamaldehyde, we have to isolate the different parts and look at the signal of each proton individually. 

The process involves simple mixing of carbonyl compounds with 10% NaBH4 supported on alumina and exposure of the reaction mixture to microwaves in a household MW oven for 0.5-2 min (Scheme 2.2-43).The useful chemoselective feature of the reaction is apparent from the reduction of traus-cinnamaldehyde (cinna-maldehyde NaBH4-alumina, 1 1 mol equivalent) the olefinic moiety remains intact and only the aldehyde functionality is reduced in a facile reaction.
