A practical synthesis of (3S,5R) oct-1-en-7-yne-3,5-diol derivatives 7 involving a catalytic enantioselective aldol reaction is described. Also a new synthesis of (3S,5R) non-1-en-7-yne-3,5,9-triol derivatives 3, starting from (2S,4S)-1,2 : 4,5-diepoxy-pentane 2 is reported.
描述了涉及催化对映选择性羟醛反应的 (3S,5R) oct-1-en-7-yne-3,5-二醇衍生物 7 的实际合成。也是(3S,5R)非-1-en-7-yne-3,5,9-三醇衍生物3的新合成,从(2S,4S)-1,2开始:4,5-二环氧戊烷2被报道。
