#第五人格空军[超话]#今天在主超看见喜欢先知的友友们在破防,多数是因为先知主线剧情,真理之下的主线剧情以及真理之下的价格。刚想安慰安慰,字打到一半,突然意识到空厨不配可怜别人[悲伤][悲伤][悲伤]我们主线剧情没进展,真理之下皮肤贵,做的又拉,还不优化 [泪][泪][泪]

#SynOpen# Amino Imidate Catalyzed Asymmetric Michael Reactions of Ketones and Nitroalkenes https://t.cn/A6opSTvo
The efficiency of an amino imidate organocatalyst was evaluated in the Michael reaction of ketones with nitroalkenes. tert-Butyl l-proline imidate was found to be a syn-selective catalyst, generating products with moderate to good enantioselectivities of up to 84% ee. The best substrates were found to be cyclic ketones and β-nitrostyrenes. The catalytic efficiency and enantioselectivity were enhanced by the addition of 10 mol% of benzoic acid.

上节课老师问最近武汉有什么好玩的,有同学说万圣节欢乐谷有活动,但是夜场关门了,所以也没什么好玩的。
老师提议说万圣节就在下周,要不要下周上课大家一起扮装?
有同学开玩笑说,如果我们答应你,但是最后都没扮装,只有老师你一个人装扮了。全班大笑
然后,虽然今天上课改线上了,但是老师be like
