(1R)- and (1S)-1-[(–)-menthoxymethoxy]-E-but-2-enyl(tri-n-butyl)stannanes(5) and (6), whose configurations at C(1) were assigned by correlation with (2R)-and (2S)-pentan-2-ol, react stereoselectively on heating with benzaldeyde to give (3S,4R)- and (3R, 4R)-4hydroxy-3-methyl-cis-1,2-enol ethers (11) and (13), respectively.
(1 R)-和(1 S)-1-[(-)-薄荷氧基甲氧基] -E -but-2-enyl(tri-n-butyl)stantanes(5)和(6),其构型在C(1 )通过与(2 R)-和(2 S)-戊烷-2-醇的相关性分配,在加热后与苯并甲醛基立体反应,得到(3 S,4 R)-和(3 R,4 R)-4羟基3-甲基-顺式-1,2-烯醇醚(11)和(13)。
