The invention relates to protected alcohol with formula (R1 - O-)mPG, wherein R1 represents a linear, straight-chain alkyl group having 26-30 C-atoms, m is 1 or 2, and PG, forming an ether group in combination with the -O- of the former primary alcohol, represents a protecting group chosen from the group of substituted methyl, substituted ethyl, substituted benzyl and (substituted) silyl groups with at least one substituent on the Si-atom being not a methyl group, in case m = 1; and a diol protecting group in case m = 2, with the proviso that PG is no saccharide. The invention further relates to process for the preparation of such protected alcohols via an organometallic cross coupling reaction.
该发明涉及具有化学式(R1 - O-)mPG的受保护醇,其中R1代表具有26-30个碳原子的线性直链烷基基团,m为1或2,PG与前述初级醇的-O-形成醚基团,表示从取代甲基、取代乙基、取代苄基和(取代)硅基团中选择的保护基,其中硅原子上至少有一个取代基不是甲基,当m = 1时;当m = 2时,为二醇保护基,但PG不是糖苷。该发明还涉及通过有机金属交叉偶联反应制备这种受保护醇的方法。
