Abstract Syntheses of long-chain hydroxy-, methoxyalkylsilanes of the type (RSi(CH 3 ) 2 OH, R m SiY 4− m with R=C 12 H 25 , C 18 H 37 and Y=OH, OMe, m =1, 2, 3) ( 5 , 6 , 7a–c , 8a–c , 9a–c , 10a–c ) and alkylsilyl glycopyranosides ( 13 , 14 , 15a–c , 16a–c ) are reported. Hydroxyalkylsilanes ( 5 , 6 , 7a–c , 8a–c ) were prepared by the hydrolysis of alkylchlorosilanes ( 1a–c , 2a–c , 3 , 4 ) with
摘要(RSi(CH 3)2 OH,R m SiY 4− m,R = C 12 H 25,C 18 H 37且Y = OH,OMe,m = 1的类型的长链羟基-甲氧基烷基硅烷的合成,2,3)(5,6,7a-c,8a-c,9a-c,10a-c)和烷基甲硅烷基吡喃葡萄糖苷(13,14,15a-c,16a-c)。羟烷基硅烷(5,6,7a-c,8a-c)是通过用NaHCO 3 -H 2 O在乙醚中水解烷基氯硅烷(1a-c,2a-c,3,4)制备的。烷基氯硅烷1a–c和2a–c与KOMe在正己烷中反应,分别得到甲氧基烷基硅烷9a–c和10a–c。烷基氯硅烷1a-c,2a-c,3和4与2,3,4,6-四-O-乙酰基-α/β-d-吡喃葡萄糖12在CH 2 Cl 2中直接反应,得到烷基甲硅烷基吡喃葡萄糖苷13、14, 15a–c和16a–c。
