Never thought i'd be one to suffer from mood swings. worst thing is, they're due to the stupidest thing - research! seems like there's barely any link, but let me explain. here's how things go down, in a somewhat flowchart form. i'm happy if do a literature search, and can find nice easy reactions with chemicals that i know that we have in lab. next step, actually locating those chemicals. we're in the midst of reshuffling, so things are a little messy. like tonight, i spent an hour hunting for a bottle of potassium t-butoxide, even going to the chemical store and our other lab. took me about an hour, with no luck. i was so engrossed in looking for the damned thing that i missed my phone ringing, and as a result, accidentally stood my friend up. what makes it worse is that he came down to NUS after work and waited over an hour for me. then, my senior spotted the bottle at the balance right next to my fume hood. how moronic is that!? so that delayed me by a fair bit. more elaboration later. back to the flowchart thing. locating all the chemicals and doing the reaction. i get super annoyed when it doesn't work out as planned, even though the plan looks sound from every angle. so as you can see, there are many many opportunities for table-flipping. and this is just substrate synthesis. not even the actual reaction, which SHOULD go smoother, since i already have somewhat of an example. but right now, my main objective is to synthesize the compound. one thing i have to be grateful about is that another scifinder search led me to stumble on the exact structure of the compound i was looking for. don't know why it didn't turn up in previous searches. so this new route is a convergent synthesis, which should give higher overall yield. the horrible thing is that according to the literature, the very first step of one branch only yields 39% desired product. but well. i just need like 10mmol overall to try a few reactions. considering that i've thrown in 50mmol and 20mmol for each respective branch, i'm optimistic. expanding the substrate scope might be troublesome though...but we'll cross that bridge at the appropriate time.
one more piece of news that crosses my mind now. i'm signing up for JLPT! test date should be this december, and i'm going for N2. the statistics aren't helping me in making my decision. so far, i know 3 people who have taken the exam. 2 are from japanese 5, and the third is a friend of a friend. i can't use the last one as reference, because it seems that she speaks japanese every day in her office. definitely not a fair comparison. as for my 2 classmates, i know one passed (he posted his results slip on facebook), and i suspect the other one failed. both of their advice is the same...read up for kanji. the one who passed said that surviving NUS japanese 5 means that N2 should be manageable, particularly for the listening component. definitely have to study though...i don't feel all that confident of passing right now. research might make it difficult, but then again, i don't have finals this semester, and the JLPT is like...3 months away. i can probably make something work in that time. i actually emailed last semester's japanese lecturer to borrow the N2 textbook. she said that while i could borrow it, it was for the lecturers' use, and that if required, i'd have to return it on demand. too troublesome. so i guess i'll be going down to kinokuniya maybe this sunday to check things out.
part of the registration process involves sending in 2 passport photos. you know what that means...time to do something which i really dislike. and in a sense, the timing works, because i need a haircut. so i guess i'll get my hair cut either tomorrow or this weekend, then find somewhere to take passport photos, then register online on monday, and send the the photos in by mail during the week. seems like i'll make the deadline with no problems.
some time ago, like a couple of years, i participated in this NUS allergy study (and got a $10 co-op voucher for participating). during that test, i found out that i'm allergic to dust mites. not sure if that's why i've been itching like mad recently. that, and i've got a lot of mosquito bites. the nights are cooler than say, a month ago, and i'm really grateful for that. might mean that mosquitoes breed more. i don't know. whatever it is, my legs feel almost as bad as during the whole sandfly episode in JC. well...just as long as it's not chemical-induced, i'm sure it'll be fine. gets annoying, though, especially when it keeps me awake.
am i forgetting anything? probably not. oh right. remember that i took an hour to hunt for that damned chemical? that means i started the reaction late. that, in turn, means that i'll have to go to school early tomorrow for the next step. the original idea was to reach by 2:00am, but upon more thought, i think i'll just wake up at 5:00am and reach by 6:00am. i trust 4 more hours shouldn't affect my reactions to that great a degree, especially since i have enough dry ice to keep them cold, and they're done at low-temperature anyway. just hope at least one of them succeeds.
