N,N-DIMETHYLFORMAMIDE DINEOPENTYL ACETAL Usage And Synthesis

Chemical Properties

Colorless to slight yellow liquid

Uses

N,N-Dimethylformamide dineopentyl acetal helps in the lactonization of ω-hydroxyacids, giving lactones of up to 16-membered rings. It can be used to convert primary alcohols to alkylating agents for use in the alkylation of thiols. It is used in the esterification of Nα-9-fluorenylmethyloxycarbonylamino acids. It was used in the synthesis of 1,3-dialkyl, benzyl and cyclohexyl barbiturate derivatives. It was used as reagent during the synthesis of L-serine and L-cystine stereospecifically labeled with deuterium at the β-position.
