  TsOH·H2O, precursors of N-Boc-imines can be converted into the corresponding α-aryl or α-alkenyl glycine derivatives under gaseous CO2 in moderate-to-high yields with a single operation. α-Isobutenyl glycine thus obtained can be further derivatized into various types of α-amino acids including N-Boc-leucine, serine, and glycine derivatives in short steps.

  在1.1当量的PhMe 2 Si-Bpin，5当量的CsF和20摩尔％的TsOH·H 2 O存在下，N -Boc-亚胺的前体可以转化为相应的α-芳基或α-烯基甘氨酸一次操作即可在气态CO 2下以中等至高收率得到各种衍生物。由此获得的α-异丁烯基甘氨酸可以在短时间内进一步衍生为各种类型的α-氨基酸，包括N -Boc-亮氨酸，丝氨酸和甘氨酸衍生物。
