Stereochemistry of aldol reaction
網頁The chemistry of aldols is dominated by one reaction, dehydration: RC (O)CH 2 CH (OH)R' → RC (O)CH=CHR' + H 2 O Hydroxypivaldehyde is a rare example of a relatively robust aldol.

網頁2002年11月11日 · The asymmetric double aldol reaction of (R)-7 with benzaldehyde was investigated. The chiral auxiliary exhibited excellent stereocontrol ability even at room temperature to afford (S,S)-diol 9 as a major product (>95% ds). 7 The doubly borylated enolates derived from c-Hex 2 BOTf and 9-BBN-OTf were rather unreactive and 14 h of … 網頁Mukaiyama Aldol Addition The use of silyl enol ethers as an enolate equivalent in Lewis acid-catalyzed aldol additions. The trimethylsilyl group is thought of as a sterically demanding hydrogen equivalent that activates …
網頁2024年1月4日 · Elimination reactions are the reverse of addition reactions. These involve elimination of two or four groups attached to adjacent carbon atoms in a substrate forming a multiple bond. An example is elimination of HX from an alkyl halide to form an alkene (Fig. 11.1 ). Fig. 11.1. The elimination of H–X from alkyl halide.
