1,3-Di(hydroxymethyl)-2-nitrobenzene: 1,3-Dicarboxylic acid-2-nitrobenzene (2.50 g, 11.8 mmol) was dissolved in THF (12.5 mL) and cooled with an ice bath. 1M Borane-THF (59.0 mL, 59.0 mmol) was then added dropwise and the reaction was stirred for 48 hours. The THF was removed under vacuum and the product was dissolved in ethyl acetate (20 mL) and washed with water (3¡Á eq. vol.). Ethyl acetate removed under vacuum and product recrystallized with ethyl acetate and hexanes (1.75 g, 81%). 1H NMR (d-DMSO): ¦Ä=7.58 (d, 2H), 7.56 (t, 1H), 5.50 (t, 2H), 4.53 (d, 4H). °´ÕÕÉÏÃæ×÷³öµÄ·´Ó¦£¬µÎ¼ÓBH3-THFµÄʱºò³öÏÖ³Áµí ÊÇÔõô»ØÊ£¿ ethyl acetate (20 mL) and washed with water (3¡Á eq. vol.)£¿×ö³öÀ´»áÓÐÕâô¸ßµÄ²úÂÊÂð£¿ ÖØ½á¾§Á½¸öÈܼÁµÄ±ÈÀý´ó¸Å¶àÉÙ°¡£¿£¿£¿ ÎÒ×ö³öÀ´Ö»ÓÐ30%µÄ²úÂÊ |
