A biomass involved rhodium-catalyzed carbonylative synthesis of furfuryl esters and tertiary amides has been developed. 5-Hydroxymethylfurfural (HMF) was used as both substrate and CO surrogate for the first time in a carbonylation reaction, and both alkyl and aryl iodides were tolerated well to afford the desired furfuryl esters in moderate to good yields. In addition, furfural was also utilized as a CO source for the synthesis of tertiary amides. A variety of tertiary amides were obtained in moderate to excellent yields with good functional groups compatibility. Notably, tertiary amines were used as the amine source through a C[sbnd]N bond cleavage pathway in the absence of additional oxidant.

By using acetyl chloride as HCl generator, the procedure for the Hoffer preparation of the α-chloro sugar 4a was significantly improved. The α-configuration of the chloro atom was confirmed by using NOE measurement. Sequential transformation of 4a to the β-anomer and to the furfuryl derivative 6 was studied.

4-Amino-7(8H)-pteridinone (5) and its 2- and 5-phenyl derivatives (6-8) are converted by the Silyl-Hilbert-Johnson method to the corresponding acylated N-8-ribosides (15-18, 23, 24).Deacylation led to the free pteridine nucleosides (19-22, 25) which can b
