Several models exist to describe chiral induction at carbonyl carbons during nucleophilic additions. These models are based on a combination of steric and electronic considerations and are often in conflict with each other. Models have been devised by Cram (1952), Cornforth (1959), Felkin (1969) and others. The Cram's rule of asymmetric induction developed by Donald J. Cram in 195… WebOct 6, 2024 · Cram's rule, proposed by Donald Cram in 1952, [1] was the earliest model proposed for rationalising the stereoselectivity of nucleophilic additions to carbonyl …
