The aminodihydroisocoumarin moiety of AI-77-B, a gastroprotective substance isolated from Bacillus pumilus AI-77, has been prepared from a convenient chiral synthon of L-erythrose by combination of chiral triflate technology and regioselective aromatic carboxylation.
AI-77-B 是一种从枯草杆菌 AI-77 中分离出来的胃保护物质,它的氨基二氢异香豆素分子是通过手性三酸酯技术和区域选择性芳香羧化技术相结合,从 L-erythrose 的简便手性合成物中制备出来的。
