A synthesis of difluorinated α-C-galactosylceramides analogs featuring an extra hydroxy group in 1′-position is reported. These compounds were prepared according to unprecedented and unusual methodologies that were previously reported by the authors on simpler substrates. Unfortunately, all four compounds, which feature different lipidic chain lengths, failed to activate iNKT cells. The question whether
报道了在1'-位具有额外羟基的二氟化α-C-半乳糖基神经酰胺类似物的合成。这些化合物是根据作者先前在较简单的底物上报道的空前和不寻常的方法制备的。不幸的是,所有四个具有不同脂链长度的化合物均未能激活iNKT细胞。到底是由于端基氧/ CF 2的转位还是由于额外的OH基的存在,这一问题仍未得到解答。
