The invention relates to protected alcohol with formula (R
1
—O—)
m
PG, wherein R
1
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.
本发明涉及带有式(R1—O—)m
PG的保护醇,其中R1表示具有26-30个碳原子的线性直链烷基,m为1或2,
PG与前面的原始醇中的—O—形成醚基,
PG表示从取代甲基、取代乙基、取代苄基和(取代)
硅基中选择的保护基,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,
PG表示二元醇保护基,但
PG不是糖苷。本发明还涉及通过有机
金属交叉偶联反应制备这种保护醇的方法。
