• other efforts relying on various resolution techniques [16][19][20][21][22][23][24][25][26]. We, however, have reported that stereocontrolled meta-functionalization of a calix[4]arene is possible via chiral oxazoline-directed ortholithiation [27][28]. This has allowed for a range of functionalized

• reaction. Results and Discussion Ortholithiation of tert-butyloxazoline calix[4]arenes The synthesis of the tert-butyloxazoline calix[4]arenes 4a/4b from carboxyl calix[4]arenes 3a/3b was achieved through one of two standard three-step methods (Scheme 2). These calix[4]arenes were then subjected to

• carbohydrate-derived chromium complexes that have been described in the literature so far. Complexes of type A and B were obtained from the corresponding glycopyranosides and were studied as substrates for chiral-auxiliary-directed asymmetric ortholithiation and as catalysts for enantioselective Diels–Alder
