Sila analogues: The first asymmetric synthesis of silacarboxylic acids with a stereogenic center at the silicon atom has been achieved from chiral nonracemic silanols, without loss of optical purity. Silacarboxylic acids can be converted into their corresponding esters using a Mitsunobu-type reaction.
