hydroxypiperidinones which werefurther dehydrated to two pyridin-2-ones in the presence of boron trifluoride etherate. Cycloaddition and regioselective reduction were combined to synthesize 1,2,3,4,6,7,12,12b-octahydroindolo[2,3-a]quinolizine and homobaclofen.
N-烷基-3-磺酰基戊二酰亚胺用 (1) 氢化钠然后用氢化铝锂或 (2) 硼氢化钠还原产生两种不同类型的区域选择性还原的羟基哌啶酮,它们在三氟化硼醚合物。环加成和区域选择性还原相结合,合成了1,2,3,4,6,7,12,12b-八氢吲哚[2,3-a]喹啉和高巴氯芬。
