Mechanism for Claisen Condensation:

Essential Organic Chemistry (3rd Edition), Chapter 13.8, Problem 17P , additional homework tip  1

  • A base abstracts a proton from the αcarbon forms enolate ion.
  • The enolate ion gets attached to the carbonyl carbon of another ester.
  • The negative charge on oxygen of the carbonyl group reforms, by removing an alkoxide ion.

Q5: Label each chiral carbon in the following molecules as R or S. Make sure the stereocenter to which each of your R/S assignments belong is perfectly clear to the grader. (8pts) R OCH 3 CI H S 2pts for each R/S HO R H !!! I OH CI HN CI R H
Calculate the proton and carbon chemical shifts for this structure
A. B. b. Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry. Which molecule is the more stable molecule, and why?
