Reduction of 5-oxo-4-phenyl-1H-4,5-dihydroindeno[1,2-b]pyridines with triethylsilane in trifluoro-acetic acid gave the corresponding 1,2,3,4-tetrahydroindeno[1,2-b]pyridines predominatly with the trans-configured substituents at atoms C(2), C(3), and C(4). Alkylation of the anionic form of the tetrahydroindenopyridines gives the N- and C(4a)-alkyl derivatives.
在三氟乙酸中用三乙基硅烷还原5-氧代-4-苯基-1H-4,5-二氢茚并[1,2- b ]吡啶得到相应的1,2,3,4-四氢茚并[1,2- b ]吡啶主要在原子C(2),C(3)和C(4)处具有反式取代基。四氢茚并吡啶的阴离子形式的烷基化得到N-和C(4a)-烷基衍生物。
