Abstract
The reactions of esters 1 and dialkylamides 8 of 3-phosphorylpropionic acid s with Grignard reagents 6 in the presence of titanium tetraisopropoxide 5 or methyltitanium triisopropoxide 11 give 1-substituted and 1,2-disubstitut ed phosphorylated cyclopropanols 7 and cyclopropylamines 12 in moderate to very good yields (37-71 and 39-86%, respectively). These useful transformat ions convincingly demonstrate the wide functional group compatibility and v ersatility of this new carbonyl group cyclopropanation.
