Chapter 21: Q17P (page 708)

What product would you expect from the reaction of butyrolactone with LiAlH4? With DIBAH?

Short Answer

Expert verified

Product formed are:.

  1. 1,4-Butanediol (with LiAlH4)

2.4-Hydroxy butanal (DIBAL-H)



Step by step solution

01

Reduction with LiAlH4

Esters are easily reduced to primary alcohols using LiAlH4. In case of cyclic esters diols are formed.

02

Reduction with DIBAL-H

Partial reduction take place in case of DIBAL-H, and reaction stops at formation of aldehydes.

The hydrolysis of a biological thioester to the corresponding carboxylate is often more complex than the overall result might suggest. The conversion of succinyl CoA to succinate in the citric acid cycle, for instance, occurs by initial formation of an acyl phosphate, followed by reaction with guanosine diphosphate (GDP, a relative of adenosine diphosphate [ADP]) to give succinate and guanosine triphosphate (GTP, a relative of ATP). Suggest mechanisms for both steps.

Propose structures for compounds that have the following formulas and IR absorptions:

(a) C6H12O2, 1735 cm-1

(b) C4H9NO, 1650 cm-1

(c) C4H5ClO, 1780 cm-1
