Research: http://science.uvu.edu/ochem/index.php/alphabetical/c-d/chromic-acid/ http://www.chem.purdue.edu/zwier/pubs/jcp_98_5362.pdf Very interesting stuff on diacetylene in space.

This could be workable with some modification. The acetylide will react with the carboxyl, so you would really need a protected alcohol or aldehyde that could be deprotected and oxidized later. For the coupling check out the Cadiot-Chodkiewcz reaction (don't ask me how it's pronounced). This reaction uses copper to assymetrically couple a haloalkyne with a terminal alkyne through a free radical mechanism. It is in March Advanced Organic Chemistry Section 4-17. Since you had to start on this last minute, you can re-post it before Monday if you like, so that you can do research on these reaction techniques. Bruce Bondurant
