17 April 2019 Problems te wing molecules using either diethyl malonate or alkyl halide or alcohol...
Propose an efficient and elegant synthesis of each of the following molecules using either diethyl malonate or ethyl acetoacetate as your starting material. You may use any alkyl halide or alcohol as your other sources of carbon, and you may use any reagent you deem necessary. CH3 EN CH₂ HCO CH, Hgc CH, CHA CH₃ -CHS
Propose a synthesis of the following derivative of diethyl malonate using reagents from the choices provided below. (From the choices provided, list the reagent(s) in order that will accomplish this transformation. No more than 4 steps are required. List your answer as a single letter (single-step transformation) or a series of letters (multi-step transformation) with no commas separating them.) Reagents available a. Eto Na g. CH2=CHCH=CHCH,Br b. CH3 CH2Br c. CH3 CH, CH, CH(CH3)Br d. (CH3)2 CHCH, CH,Br e. CH3...
Using benzene, acetylene, dimethyl malonate, pyrrolidine
(all other amines must be made from these other
sources), CO2, CN-, ethylene
oxide and/or monofunctional alcohols of 5 C or less as your sources
of carbon to be incorporated into the molecules, show how your 3
problems could be synthesized (see list below, and the attachment).
Try to use reactions from the indicated chapters if you
can. Please upload your work (prefer as pdf) as an
attachment to assignment. Due by final (5/2)....

Synthesis using Carbonyla-Substitution Chemistry Preamble This experiment involves the synthesis of target molecules using a-substitution chemistry. You are assigned two target molecules, one of which is best synthesized by an alkylation approach, while the other is best synthesized by an addition or condensation approach. My two target molecules are number 2 and number 12 in the last page. You must do the following: 1. Perform a retrosynthetic analysis on the two target molecules assigned to you. In each case the...
Page 1 Synthesis using Carbonyl O-Substitution Chemistry Preamble This experiment involves the synthesis of target molecules using a-substitution chemistry. You are assigned two target molecules, one of which is best synthesized by an alkylation approach, while the other is best synthesized by an addition or condensation approach. You must do the following: 1. Perform a retrosynthetic analysis on the two target molecules assigned to you. In each case the organic starting material (what you have to work backwards toward) depends...
13 SN1: Synthesis of tert-Butyl Chloride Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as SNI (substitution, nucleophilic, unimolecular) and S 2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Syl route, primary alcohols follow the Sy2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Syl reaction involves rapid protonation of the alcohol, followed by...

**(left structure)****(right
structure)**
The two structures for the assignment are above and
the task is:
1. Perform a retrosynthetic analysis on the two target
molecules assigned to you. In each case the organic
starting material (what you have to work backwards toward) depends
upon the target. For the structure given above (structure on left),
the starting material is either malonic ester or acetoacetic ester
and any halide. For the structure given above (structure on right),
the starting material is any...
