Lactam and Amide Acetals. 52. Reaction of Dimethylformamide Diethylacetal with 2,2-Dimethyl-4,6-dioxo-1,3-dioxane (Meldrum's Acid)

Depending on the conditions of carrying out the reaction of dimethylformamide diethylacetal with the Meldrum's acid, either 2,2-dimethyl-4,6-dioxo-5-(N,N-dimethylaminomethylene)-1,3-dioxane or N,N,N',N'-tetramethylformamidinium salt of 2,2-dimethyl-4,6-dioxo-5-(2,2-dimethyl-4,6-dioxo-1,3-dioxan-5-yl)methylene-1,3-dioxane are formed.The two compounds can reacts with primary amines to form N-substituted 2,2-dimethyl-4,6-dioxo-5-aminomethylene-1,3-dioxanes.

Synthesis of the microbial elicitor syringolide 2 multiply labelled with deuterium

Multiply-deuterated syringolide 2 3 was prepared from D-xylulose and 8- bromooctanoic acid by a convergent route based on our previously reported biomimetic synthesis of this microbial elicitor. Key steps were the thermal acylation of the anisylidene-prot
