摘要:
A domino on-water, in-water process has been developed for the rapid and efficient synthesis of (+/-)-columbianetin. This highlights the operational simplicity of on-water chemistry. The domino process forms the key step in the synthesis of the columbianetin-containing natural products (+/-)-columbianetin acetate, (+/-)-zosimin, (+/-)-libanorin and (+/-)-angelmarin.
