Dialkylphosphites
WebDialkylphosphites (2a-c) or trialkylphosphites (3a-c) were reacted with 2- (thiophen-2-yl)-1H-indole-3-carbaldehyde (1) yielding the corresponding α-hydroxyphosphonate adducts (7a-7c). The reaction of compound 1 with the ylidenetriphenylphosphoranes (4a-4c) proceeds via Wittig mechanism giving the corresponding ethylenes (E, 8a-c). Alkyl phosphates belong to a group of organic compounds called organophosphates. They are esters of phosphoric acid H3PO4 and corresponding alcohol. For example, the formula of methyl phosphate is CH3-H2PO4, dimethyl phosphate – (CH3)2HPO4 and trimethyl phosphate – (CH3)3PO4. Alkyl phosphates are widely distributed in nature, and form the basis of most biological processes. For example, high energy metabolites such as ATP and PEP are alkyl phos…
