How to use this set
[PhCH2CH2Br + (CH3)3SiCl → PhCH=CH2 + (CH3)3SiBr + HCl]
Classify the following reaction as a pericyclic reaction:
A tetracyclic compound with a congested tertiary C–H bond at the benzylic position adjacent to a piperidine ring. advanced organic chemistry practice problems 2021
Maintain low temperature. This ensures kinetic control. Step 3: Add methyl iodide ( CH3Icap C cap H sub 3 cap I
: The diene is (2E,4E)-hexa-2,4-diene (electron-rich). The dienophile is methyl acrylate (electron-deficient).
: The incoming methyl group forces the carbonyl oxygen to rotate into a tetrahedral intermediate. After protonation, the major product is the (2S,3R)-3-phenylbutan-2-ol diastereomer. 3. Retrosynthetic Analysis and Multi-Step Total Synthesis How to use this set [PhCH2CH2Br + (CH3)3SiCl
