- A novel method for preparing isocyanides from N-substituted formamides with chlorophosphate compounds
-
Treatment of N-substituted formamides with chlorophosphate compounds such as PhOPOCl2, EtOPOCl2, Me2NPOCl2, and (PhO)2POCl and tertiary amines such as triethylamine, pyridine, and N,N-diisopropylethylamine produced the corresponding isocyanides in high yields. This method can be used to prepare various alkyl and aryl isocyanides. Georg Thieme Verlag Stuttgart · New York.

- Total syntheses of Tardioxopiperazine A, Isoechinulin A, and Variecolorin C
-
Chemical equations presented. First total syntheses of the isoechinulin-type alkaloids: Tardioxopiperazine A, Isoechinulin A, and Variecolorin C have been achieved from a common key intermediate 5, which was derived from a regiocontrolled Stille cross-coupling reaction of an allylindium reagent.
