Abstract

The reaction of (substituted) alkenylidene-hydrazinecarbothioamides with 2-(1,3-dioxo-2,3-dihydro-1H-inden-2-ylidene)propanedinitrile led to the formation of 1,3-dioxospiroindene[1,3]-thiazine and thioxoindeno[2,1-d]imidazolone derivatives in modest yields. In addition, 1,3-dihydroxyindan-2-ylidenepropanedinitrile was found. Explanations of these conversions involving nucleophilic reactions and condensations are presented.

Acylation of ammonium 3-deoxy-n-D-manno-Z-octulopyranosonate (la) leads to the formation of peracetylated 3-deoxy-a-D-manno-2-octulopyranosono-1,5-lactones (3a,b). The proposed structures were confirmed by independent syntheses. The 1,7-lactone was not formed even when only OH-7 was available for la
