Abstract
Chiral or achiral (Z)-crotylorganoboron compounds add preferentially a nti to N-(tert-butoxycarbonyl)-amino aldehydes. N-(tert-Butoxycarbonyl )prolinal 3 presents a remarkably high diastereofacial selectivity. Do uble stereodifferentiation, starting from compound 3, allows complete diastereoselective access to the gamma-amino-beta-hydroxy-alpha-methyl acid dolaproine 1 present in the antiproliferative dolastatin 10.
