Herein, we report the first examples of the synthesis of pyrroloindolines by means of (3 + 2) dearomative annulation reactions between 3-substituted indoles and highly reactive azaoxyallyl cations. Computational studies using density functional theory (DFT) (B3LYP-D3/6-311G++) support a stepwise reaction pathway in which initial C-C bond formation takes place at C3 of indole, followed by ring closure to give the observed products. Insights gleaned from these calculations indicate that the solvent, either TFE or HFIP, can stabilize the transition state through H-bonding interactions with oxygen of the azaoxyallyl cation and other relevant intermediates, thereby increasing the rates of these reactions.

The indole (1) and chroman analogs (2) of mevinolin and their 6S diastereomers 15c and 25d were synthesized in several steps starting with methyl (R)-3--4-formylbutyrate (12) and 2-(indol-3-yl)ethanol (3) or 6-methoxychroman-4-one (16), respectively.Compounds 1 and 2 inhibited moderately the HMG-CoA reductase.The diastereomers 15c and 25d were shown to be inactive. - Keywords: HMG-CoA reductase inhibitors / 3-Indolylheptanoates and -acetates / 4-Chromanylheptanoates and -acetates
