4 Complete one of the extra credit (4 pts). two syntheses below. (4 pts) if you complete both, it...
Complete Multi step synthesis:
This one is for extra credit. Hint: With Claisen and acetoacetic ester chemistry, you can assemble four two-carbon pieces ?? sole carbon source
Extra Credit Propose an elegant and efficient synthesis of the molecule show below. You may use alcohols of 4 carbons or less as your only source of carbon. H3C CH3 HBr CHs
need help
1. (16 pts.) Complete two of the three multistep syntheses below. You will not recieve extra credit for doing all three. You do not need to provide an arrow pushing mechanism. Be as specific as possible and draw a star next the two you would like me to grade. Mind your stereochemistry. -OH = -ОН HEH - -Li
organic chemistry 353, show the mechanism in detail please.
thanke you
8. (18 pts.) Complete two of the three multistep syntheses below. You will not recieve extra credit for doing all three.You do not need to provide an arrow pushing mechanism. Be as specific as possible and draw a star next the two you would like me to grade NH2 H NH 2 NH2 SoH
5. Provide a synthesis of the following compounds from the given starting material. (Complete any two for 8 pts each-if you do a third, it w'll be treated as extra credit.) NO2 From benzene Br From benzene as the source of at least one aromatic ring H2N Extra Credit: Explain why p-methoxybenzyl bromide (A) is more reactive than p-nitrobenzyl bromide (B). Be thorough. (6 pts) 6. O2N
